Due monday, november 26, 2012 (start of class) Chapter 10 suggested problems: ch 10: 3, 19, 25, 69, 75 (practice setting up all as a hypothesis test). Confidence interval practice problems: ch 9: 41, 47, 49. Directions: this homework set should be turned in individually. Each problem may be presented in typed or hand-written form. Clearly show all steps and box any specific answers (do not box graphs) to receive full credit. Assigned problems: unless otherwise stated, you may use an alpha level of 0. 05 as the level of significance. You may use excel to calculate means and standard deviations, but state the function used. Hypothesis tests must complete all steps including the conclusion (reject/fail to reject, probability or statistic comparison, and real-life interpretation) for full credit. 8 homework, test the hypothesis that there is no difference in weight between machines a and b. 8 homework, test the hypothesis that the standard deviation is 0. 05 (this is the tolerance).
