Cincinnati Paint Company sells quality brands of paints through hardware stores throughout the United States. The company maintains a large sales force who call on existing customers and look for new business. The national sales manager is investigating the relationship between the number of sales calls made and the miles driven by the sales representative. Also, do the sales representatives who drive the most miles and make the most calls necessarily earn the most in sales commissions? To investigate, the vice president of sales selected a sample of 25 sales representatives and determined: The amount earned in commissions last month (y) The number of miles driven last month (x1) The number of sales calls made last month (x2) The information is reported below.

The manager of the order-distribution center for North-woods Backpackers has a company directive to downsize his operation. He has decided to conduct work sampling studies of employees in the order-processing department, the ware-house area, and the packaging area. In the warehouse area he has 17 employees who locate items, pull them, and put themon conveyors to the packaging area. A work sampling study was conducted over a five-day period to determine the pro-portion of time warehouse employees were idle, and out of the 50 random observations, 400 employees were idle.a. How many observations should be taken if the managerwants to be 90% confident the estimate is within 5%of the actual proportion of time a warehouse employeeis idle?b. The manager also conducted a work sampling study of the packaging area and discovered that the 28 employ-ees were idle approximately 37% of the time. How might the manager redesign his operation to downsizeand be more efficient?
Slamet is a young entrepreneur who started his business by opening 5 “Bebek Mas Slamet” restaurants in different locations, namely in Blok S, Blok M, Blok A, Senayan, and Depok areas. Because it is still in its infancy, Slamet still frequently observes data on the number of sales portions of Fried Duck which is the mainstay of the restaurant "Bebek Mas Slamet".

(A) Socially conscious investors screen out stocks of alcohol and tobacco makers, firms with poor environmental records, and companies with poor labor practices. Some examples of "good," socially conscious companies are Johnson and Johnson, Dell Computers, Bank of America, and Home Depot. The question is, are such stocks overpriced? One measure of value is the P/E, or price-to-earnings ratio. High P/E ratios may indicate a stock is overpriced. For the S&P Stock Index of all major stocks, the mean P/E ratio is ? = 19.4. A random sample of 36 "socially conscious" stocks gave a P/E ratio sample mean of x = 17.6, with sample standard deviation s = 5.6. Does this indicate that the mean P/E ratio of all socially conscious stocks is different (either way) from the mean P/E ratio of the S&P Stock Index? Use ? = 0.05 i-What is the value of the sample test statistic? (Round your answer to three decimal places.) (B)Let x be a random variable that represents red blood cell count (RBC) in…

A local West Lafayette commercial bank issues Mastercard credit cards. As a part of its annual review of the profitability of each type of credit card, the bank randomly samples 36 customers to measure the average annual charges per card. A random sample of 36 Mastercard accounts shows the following annual spending per account (in USD): 2869 3770 2854 2750 2574 2972 2549 3267 3013 2707 2794 1189 2230 2178 3032 3485 2679 2010 1994 2768 3853 2064 3244 2738 2807 2395 3405 3006 3368 2691 1996 3008 2518 2674 2730 3719 1. Based on these randomly sampled accounts, what is the best point estimate of the true mean annual spending for Mastercard account holders? 2. Develop a 95% confidence interval estimate of the mean annual spending. Interpret this range. 3.

Human blood is classified by the presence or absence of three main antigens (A, B, and Rh). When a blood specimen is typed, the presence of the A and/or B antigen is indicated by listing the letter A and/or the letter B. If neither the A nor the B antigen is present, the letter O is used.The following table gives the percent of a country's population having each of the eight possible blood types in the sample space. Note that the presence or absence of the Rh antigen is indicated by the symbols + or −, respectively. Blood Types A+ A− B+ B− AB+ AB− O+ O− Percent 35.9 6.3 9.5 2.5 3.2 0.8 37.4 4.4 (a) What is the probability that a person selected at random from the population has a blood type that is type A given that the person is Rh−? (Round your answer to two decimal places.)(b) What is the probability that a person selected at random from the population has a blood type that is Rh+ given that the person is type B?
