A family of mutual funds maintains a service that allows clients to switch money among accounts through a telephone call. It was estimated that 3.2% of callers either get a busy signal or are kept on hold so long that they may hang up. Fund management assesses any failure of this sort as a $10 goodwill loss. Suppose that 2,000 calls are attempted over a particular period. a. Find the mean and standard deviation of the number of callers who will either get a busy signal or may hang up after being kept on hold. b. Find the mean and standard deviation of the total goodwill loss to the mutual fund company from these 2,000 calls.

A calculus instructor uses computer-aided instruction and allows students to take the midterm exam as many times as needed until a passing grade is obtained. Following is a record of the number of students in a class of 50 who took the test each number of times. Students Number of Tests 22 1 15 2 8 3 5 4 a.Find the expected value of the number of tests taken. b.Compute the variance and the standard deviation of the number of tests taken.
Based on a sample of 80 recent MBA graduates (40 male and 40 female), the following information was made available regarding their annual salaries. The standard deviation of salaries for the male graduates was $40,000 and that for the female graduates was $25,000. a.) For the male graduates, what is the probability of obtaining a sample mean salary within $10,000 of the population mean? Show work. b.) Consider the same question in (a) but for the female graduates. In which case, males or females, do we have a higher probability of obtaining a sample estimate within $10,000 of the population mean? Why? Show work. c.) Suppose that the sample mean salary of females is $125,000. Develop a 95% confidence interval estimate for the mean salary of all female graduates.
A firm has modeled its experience with industrial accidents and found that the number of accidents per year is related to the number of employees by the regression equation Y = 6.6 + 0.098*X. R-Square is 0.72. The regression is based on 20 annual observations. The firm intends to employ 480 workers next year. How many accidents do you project? 47.04 accidents 8.66 accidents 53.64 accidents 72% of the 480 workers 28.56 accidents
Using traditional methods, it takes 101 hours to receive a basic driving license. A new license training method using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique with 100 students and observed that they had a mean of 102 hours. Assume the variance is known to be 16. A level of significance of 0.05 will be used to determine if the technique performs differently than the traditional method. Find the value of the test statistic. Round your answer to 2 decimal places. Enter the value of the test statistic.

You are a food specialist in a company that specializes inrefrigerated delicacies, and one of your brands requires beingmaintained at a temperature of 5°C. You determine averagewater activity (aw) at this temperature to be 0.2. One day, you are informed that the cooling systems onone of the delivery trucks carrying your company’s productsmalfunctioned while en route to its destination and it would notbe fixed until the next delivery. The driver has informed you thatthe temperature in the delivery bay of the truck is averaging55°C. You estimate a heat of sorption (Q) of 19 kJ/mol. Calculate the water activity of the brand at this elevatedtemperature and comment on it’s integrity. Should the deliverystill push through? Or should the products be recalled anddisposed
Jon is preparing a newsletter to his clients. As part of his newsletter, he reports their economic outlook for the coming year. He samples 85 of his clients, and they report that they expect to hire 7.8 new employees during the coming year. Last year all of his clients averaged 6.3 hires with a standard deviation of 4.0. Jon wants to know if the expected number of new hires has significantly increased at the 5% significance level. What are the null and alternate hypotheses?
