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):…

subject: Quantitative Analysis For Business Please answer both. Use the image for question 10. 10. A hair stylist used market research to learn that members of different age groups have different preferences for positive and negative advertisements. Research participants could mark their preference for only one of the two ads. The positive ad presented a model with attractive hair supported by a message affirming the decision to schedule hair styling services, whereas the negative ad displayed a model with unattractive hair supported by a message describing the need for hair styling services. Results are shown in the table below: What is the probability of a site visitor either preferring negative ads or being a member of age category B? 6% 62% 56% 68% 93% 11. A hair stylist averaged 21 clients per day over the past several months. Typically four of these clients have been male. What is the probability for the total number of female clients the hair stylist can expect…
An economist was interested in the relation between the disposable income of a family and the amount of money used for food per month. He did a preliminary study on eight randomly selected lower income families. (Each family was of the same size; father, mother and two children). The economist’s data are given in the table below. Food cost (Y) (in hundreds of rand) 55 60 42 40 37 26 39 43 Family disposable income(X) (in hundreds of rand) 30 36 27 20 16 24 19 25 Find the regression linear equation. What is the predicted food cost if the family disposable income is R1800? Find the correlation coefficient & Interpret r. Find the Coefficient of Determination & Interpret the R2.
Beagle Clothiers uses a weighted score for the evaluation and selection of its suppliers of trendy fashion garments. Each supplier is rated on a 10-point scale (10 = highest) for four different criteria: price, quality, delivery, and flexibility (to accommodate changes in quantity and timing). Because of the volatility of the business in which Beagle operates, flexibility is given twice the weight of each of the other three criteria, which are equally weighted (the sum of the four weights equals 1). The table shows the scores for three potential suppliers for the four performance criteria. Supplier A Supplier decimal place.) Criteria 1. Price 2. Quality 3. Delivery 4.

For the following situations, identify the test you would run to analyze the data: A marketing firm producing costumes is interested in studying consumer behavior in the context of purchase decision of costumes in a specific market. This company is a major player in the costume market that is characterized by intense competition. The company would like to know in particular whether the income level of the consumers (measured as lower, middle, upper middle, and upper class) influences their choice of costume type. They are specifically focused on four types of costumes (funny costumes, scary costumes, clever costumes, and boring costumes). a. Chi-Square Goodness of Fit b. Frequencies c. Descriptive Statistics d. Chi-Square of Independence
Management of a major company has made the following assumptions regarding their consumer profile. Over 60% of all shoppers are women Less than 40% of our customer primarily make purchases through online resources The average age of the purchasers of product B is below 45 years. The average weekly purchase of the top selling product A exceeds $50. The company hired market researchers to determine the validity of their consumers' demographic assumptions. The researchers conducted survey and focus groups to evaluate the purchasing pattern of the company's current consumers. In a survey of 400 consumers, 252 respondents were women and 148yrespondents indicated they purchase the company's products online. The average age of the respondents was 44 years with standard deviation of 10 years. The average weekly purchase of top selling products A and B by the respondents were $52 with standard deviation of $10.5 and $60 with standard deviation of $22.0 respectively. Determine which of the…
