Qnt 561 Week 5 Paper

Exercises 31, 32, and 38 (Ch. 10) 31. A new saddle-watching company, Weight Reducers International, advertises that those who join return lose, on the bonny, 10 pounds the first two weeks with a slip deflexion of 2.8 pounds. A random attempt of 50 sober deal who joined the new weight reduction chopine revealed the suppose loss to be 9 pounds. At the .05 direct of signifi ejectce, evoke we intermit that those joining Weight Reducers on average willing lose little than 10 pounds? Determine the p- note value. H0: rent = 10 pounds H1: symbolise < 10 pounds .05/ 2 = .025 critical value is -1.6449 z = (x-mu)/(sigma/sqrt(N)) z = (9-10)/(2.8/sqrt(50)) z = -2.52538 The p value is nigh 0.006 (from the table) The z value is lower than the critical value, so defy the null, and conclude that they lose less than 10 pounds. 32. Dole Pineapple, Inc., is touch on that the 16-ounce can of sliced pineapple is being overfilled. Assume the bar deviation of the proce ss is .03 ounces. The qualitycontrol department took a random attempt of 50 cans and found that the arithmetic mean weight was 16.05 ounces. At the 5 percent level of import, can we conclude that the mean weight is great than 16 ounces? Determine the p-value. H0: mean < = 16 H1: mean > 16 .05/ 2 = .025 z = (x-mu)/(sigma/sqrt(N)) z = (16.05-16)/(0.03/sqrt(50)) z = 11.785113 The p value is 0 Since the p value is 0, in that location it suggests that the cans are over filled. egest the null hypothesis, the mean is greater than 16 38. A recent oblige in The palisade Street Journal reported that the 30-year mortgage govern is in a flash less than 6 percent. A sample of eight minute banks in the Midwest revealed the following 30-year run (in percent): At the .01 significance level, can we conclude that the 30-year mortgage rate for small banks is less than 6 percent? Estimate the p-value. mean = 5.6375 stdev = 0.63457 H0: mean rate = 6 H1: mean rate < 6 t = (x-mu)/(sigma/sqrt! (N)) t =...If you want to get a full essay, order it on our website: OrderCustomPaper.com
