16 con't. b.) The mean and the standard deviation of a sample of 65 customer satisfaction ratings are 42.95 and 2.6424, respectively. Use the critical value to test the hypotheses you set up by setting ? = .01. Test statistic ___ Critical Value _ Conclusion _ 17. For a test statistic of 1.84, a.) compute the p-value. p-value _ b.) Use the p-value to carry out the test by setting ? equal to .10, .05, .01, and .001. Conclusion for ? = .10 _ Conclusion for ? = .05 _ Conclusion for ? = .01 _ Conclusion for ? = .001 _ 18. A company randomly selects 22 sales trainees who are randomly divided into two experimental groups – one receives type A and other type B training. The salespeople are then assigned and managed without regard to the training they have received. At the year’s end, the manager finds the following results: A group B group Average Weekly Sales $1,500 $1,300 Standard Deviation 225 251 a.) Set up the null and alternative hypotheses needed to attempt to establish that type A training results in higher mean weekly sales than does type B training by more than $20. b.) Assume equal variance. To compare the two populations, D? equals: _____
