A university engineering department has introduced a new software package called SOLVIT. To save money, the university’s purchasing department has negotiated a bargain price for a 4 user license that allows only 4 students to use SOLVIT at any one time. It is estimated that thsi should allow 90% of students to use the package when they need it. The student's union has asked for more licenses to be bought since engineering students report having to queue excessively to use SOLVIT. As a result the computer Centre monitors the use of the software. Their findings show that on average 20 students are logged on at peak times and 4 of these want to use SOLVIT. Was the purchasing department estimate correct? Answer this by yes or no and show your proof why you choose yes or no.

Due to the Coronavirus Pandemic, major apparel industries like Nike took historical losses in 2020. Entering 2021, Nike has closely been monitoring sales of long-standing shoe re-releases, whose current sales determine if Nike will continue to produce them. Nike’s new re-release of the Air Max 97 SE and Nike Air Force 1s has helped their sales jump significantly early in 2021. Nike wants to calculate both sales numbers for the year, and compare them to last year’s performance during the same fiscal quarters. Over the past 14 weeks, Nike recorded an average of 5.7 million sales this fiscal quarter with a standard deviation in sales of .65 million for Air Max 97 SE. Nike’s Air Force 1s recorded an average of 6.2 million sales with a standard deviation of 1.3 million in sales. With an alpha level of .05, construct a hypothesis test to see if there is a difference in sales during the fiscal period.
A jar of 'virtual' jelly beans sat on the Austin's desk. Issac was very hungry so he helped himself to half of the jelly beans. • Bisma forgot to bring a snack for recess so she ate a third of what was left in the jar. • Zoe saw Bisma eating jelly beans at recess so when she came back into the room she took a fourth of the remaining jelly beans. • When Kaleb returned from his break he quickly sat down and got organized so while others were getting ready Kaleb helped himself to six jelly beans from the jar. Yasmine was hoping to get some too but when she went to the jar, there were only three left in the jar. She quickly ate those up. How many jelly beans were there to begin with?
Charity Navigator is America's leading independent charity evaluator. The data in the Excel Online file below show the total expenses ($), the percentage of the total budget spent on administrative expenses, the percentage spent on fundraising, and the percentage spent on program expenses for 10 supersized charities. Administrative expenses include overhead, administrative staff and associated costs, and organizational meetings. Fundraising expenses are what a charity spends to raise money, and program expenses are what the charity spends on the programs and services it exists to deliver. The sum of the three percentages does not add to 100% because of rounding. Construct a spreadsheet to answer the following questions.

COVID-19 (novel corona virus) took the world by surprise in late 2019. By early 2020, nearly all countries worldwide were affected.Early reports from the US Centers for Disease Control and Prevention (CDC) estimated that approximately 23.9% of infected patients in the United States age 85 years and older had died. This figure is known as the mortality rate of the virus for this age group.Suppose a sample of 1140 infected patients in the United States age 85 years and older were randomly selected and 274 of the patients were known to have died.Use the p-value method to determine if the sample data support the conclusion that the mortality rate of patients age 85 years and older is greater than 23.9%. Let α=0.02α=0.02. Determine the test statistic for the hypothesis test. Round the solution to two decimal places.Determine the p-value for the hypothesis test. Round the solution to four decimal places.
Two firms, Gene's Gloves and Wally's Wallets, have factories near a lake. Both firms use a chemical for tanning leather. Some of this chemical runs into the lake. Each year Gene's Gloves dumps 15,000 gallons and Wally's Wallets dumps 25,000 gallons into the lake. A new study has found that fish and other wildlife are negatively impacted by this chemical. The government has decided to cap the amount that the factories can dump into the river at 10,000 gallons per year. For an addition $1 per gallon, Wally's Wallets is able to substitute each gallon of harmful chemical for one gallon of a harmless alternative. Gene's Gloves needs to use the harmful but more effective chemical for production. It costs $3 per gallon to safely dispose of the harmful chemical. Assume that Gene's Gloves and Wally's Wallets maintain the same level of production under the new environmental restrictions. 1. Suppose the government gives each firm the right to dump 5,000 gallons each. If the firms cannot buy or…

A company makes parts that cost $35.00 in material and labor. 92% of the parts are produced defect free and are sold for full price at $110 each. 2% of the parts made must be scrapped. Scrap parts are sold for $8.00 each. The remaining 6% of the parts made must be reworked at a cost of $12.00 each. After rework 1% still must be scrapped and the other 5% is sold at a discounted price of $90 each. a. Draw the tree diagram showing the quality cost situation. b. Determine the earnings per part. c. Determine the cost of poor quality (COPQ). d. Determine the earnings per part and COPQ if the rework operation was shut down and the parts that required reworking were just sold for scrap instead.

A typical high school student consumes 67.5 pounds of sugar per year. As part of a new nutrition plan, each member of a track team plans to lower the sugar he or she consumes by at least 30% for the coming year. Assuming each track member had consumed sugar at the level of a typical high school student and will adhere to this plan for the coming year, what is the maximum number of pounds of sugar to be consumed by each track team member in the coming year? 44 47 54 66
