urgent QUESTION 4Problem 1d:XYZ Corporation develops a wide range of products for its target market. Overall, 25% of its existing products are considered by the marketingdepartment to be successful (S) and 75% are unsuccessful.The company is using a panel of potential customers to evaluate existing product designs, with the objective to improve the success rate of futureproducts. Of the existing products, 80% of successful products (S) received good reviews (G), and 10% of unsuccessful products received goodreviews.The customer panel is also used to evaluate a number of new product designs, for which the marketing department has no data to determine if theproduct will be successful or Bot. Assume that the population of new product designs has the same probability distributions as those of the existingproducts. You are asked to determine: Of the new product designs that receive a good review, what proportion would be successful?(d) Give your proportion as a percentage with 2 decimals

Introduction: Denote the event of obtaining a successful product as S, so that the event for having…

Overhead Door (OD) Corporation’s founder, C. G. Johnson, invented the upward-lifting garage door in 1921 and the electric garage door opener in 1926. Since then OD has been a leading supplier of commercial, industrial, and residential garage doors sold through a nationwide network of more than 450 authorized distributors. They have built a solid reputation as a premier door supplier, commanding 15 % share of the market. Suppose that customers assess door quality first in terms of the ease of operation, followed by its durability. The quality improvement team (QIT) might then assign an engineering team to determine the factors that contribute to these two main problems. Smooth operation of a garage door is a critical quality characteristic that affects both problems: If a door is too heavy, it’s difficult and unsafe to balance and operate; if it’s too light, it tends to buckle and break down frequently or may not close properly. Suppose the design engineers determine that a standard…
In order to take advantage of the burgeoning public interest in sustainability, Klorax has developed a nonsynthetic line of natural cleaning products called GreenClean. One of the first sustainable products Klorax introduced was a natural cold-water detergent. The company has now gathered several years’ worth of sales data for this product in order to develop various forecast models. The company’s marketing department believes that sales increase when there are several major environmental (i.e., “green”) episodes in the national media, such as a government energy report, an increase in gasoline or energy prices, an oil spill, a pollution episode, a company getting positive press for undertaking a major green project, etc. Therefore, the marketing department wants to develop a linear regression forecasting model that relates the number of green episodes reported monthly in the national media to monthly sales of the detergent. The marketing department had several staff members go through…
The Simple Solution to Traffic A study in 2017 showed that Metro Manila has the 3rd worst traffic among its Southeast Asian neighbors. Government authorities are receiving several complaints from commuters due to the worst transport connectivity and endless queueing and congestions among rail transit stations. In this regard, aligning projects for the improvement of the traffic system as part of the "Metro Manila Dream (MMD) Plan" was set into motion. However, media reports claimed that many commuters did not feel any improvement in the current traffic situation in the Metro, especially in Epifanio Delos Santos Avenue (EDSA). The chair of the Metro Manila Development Authority (MMDA) is keen to verify if the road traffic conditions are fairly improving in EDSA despite various media reports. In the past, the recorded vehicular traffic speed in EDSA shows about 15 kph, on the average. To do this, the MMDA deployed speed measuring radars in which the traffic speeds of 200 randomly sampled…
Zeikia has just been named the director of alumni relationships at a local university. Alumni donations are an important source of revenue for colleges and universities. If administrators could determine the factors that could lead to increases in the percentage of alumni who make a donation, they might be able to implement policies that could lead to increased revenues. Research shows that students who are more satisfied with their contact with teachers are more likely to graduate. As a result, one might suspect that smaller class sizes and lower student/faculty ration might lead to a higher percentage of satisfied graduates, which in turn might lead to increases in percentage of alumni who make a donation. Zeikia is feeling an extra pressure to increase total giving to the university because of recent budget cuts. Zeikia is also feeling pressured to increase the percentage of alumni to give. Zeikia found this new metric called average alumni giving rate U.S. News & World Report.…
State University has increased its tuition for in-state and out-of-state students in each of the past 5 years to offset cuts in its budget allocation from the state legislature. The university administration always thought that the number of applications received was independent of tuition; however, drops in applications and enrollments the past 2 years have proved this theory to be wrong. University admissions officials have developed the following relationships between the number of applicants who accept admission and enter State and the cost of tuition per semester (in-state) (out-of-state) The university would like to develop a planning model that will indicate the in-state and out-of-state tuitions, as well as the number of students that could be expected to enroll in the freshman class. The university doesn’t have enough classroom space for more than 1,400 freshmen, and it needs at least 700 freshmen to meet all its class-size x2 = 35,000 - 6t2 x1 = 21,000 - 12t1 (xi) (ti):…
Suppose you have been hired as a management consultant by a major oil company to help it optimally price gasoline at its service stations. Your client would like your team to perform a study on customers' gasoline purchasing habits when they notice an increase in the price of gas. You have access to the following groups of people: Group Description Number in Group People who have not noticed a gas-price increase 30 People who drive electric cars 35 People who have recently noticed a gas-price increase 80 People who ride their bikes to work 20 People who ride the bus 100 To set up your experiment on how price-increase awareness impacts customer behavior, you would have ______ people in your treatment group and ______ people in your control group.

One major factor in low productivity is the amount of time wasted by workers. Wasted time could include things such as time spent waiting for more material and equipment, cleaning up mistakes, and performing any other activity not related to production. In a project designed to examine this problem, a consultant took a survey of 200 workers in companies that were classified as successful (on the basis of their latest annual profits) and another 200 workers from unsuccessful companies. The amount of time (in hours) wasted during a standard 40-hour workweek was recorded for each worker. Do these data provide enough evidence at the 5% significance level to infer that the amount of time wasted in unsuccessful firms exceeds that of successful ones? To answer this question, the consultant ran several analyses and provided the out below. Note that none of these analyses might be correct. A. H0: (μ1 - μ2) = 0 H1: (μ1 - μ2) > 0 B. H0: μD = 0 H1: μD > 0 C. H0: μD = 0…

Suppose when you add flexibility to your model by adding higher-order terms or more predictor variables that you begin to see the test or validation error (MSE or SSE evaluated on the test or validation set) begin to increase away from the training error. What kind of a problem are your models experiencing?
Floyd Distributors, Inc., provides a variety of auto parts to small local garages. Floyd purchases parts from manufacturers according to the EOQ model and then ships the parts from a regional warehouse direct to its customers. For a particular type of muffler, Floyd's EOQ analysis recommends orders with Q* = 20 to satisfy an annual demand of 180 mufflers. Floyd's has 250 working days per year, and the lead time averages 15 days.Note: Use Appendix B to identify the areas for the standard normal distribution. What is the reorder point if Floyd assumes a constant demand rate? If required, round your answer up to the nearest whole number. r = fill in the blank 1 Suppose that an analysis of Floyd's muffler demand shows that the lead-time demand follows a normal probability distribution with µ = 12 and σ = 2.2. If Floyd's management can tolerate one stock-out per year, what is the revised reorder point? If required, round your answer up to the nearest whole number. r = fill in the blank…
The coronavirus epidemic is principally a human catastrophe, affecting millions of people worldwide. The coronavirus 2019 (COVID-19) pandemic has brought major disruptions worldwide, with further impacts yet to be felt. For many businesses, operations are curtailed or dramatically shifted, and supply chains are disrupted (Charles, 2020). The COVID-19 pandemic has advanced rapidly since January 2020, with overwhelming consequences to people and businesses throughout the world. The Institute of Chartered Accountant of England and Wales (ICAEW, 2020) reports that COVID-19 is not just a world health emergency; it is an economic one too. Also in the view of the audit giant Ernst & Young (2020), businesses are dealing with lost revenue and disrupted supply chains and there has been significant volatility in financial markets. As the number of cases of the COVID-19 increases, the focus of companies must be on limiting the direct impact on employees and customers while also supporting…
