1) One of the first steps when performing Hypothesis Testing is: Step 0: Minimize extraneous variability (PF-CE-CN-SOP-EP), where PF stands for: ________________________________________

2) For the stated pair of hypotheses listed below what is the correct Hypothesis test? H0: = 0 H1: 0 a. Wilcoxon Test b. Two Sample T-Test c. Test for One Proportion d. One Sample T-Test

3) A Two-Sample T-Test was conducted comparing: Location A, Location B. Listed below is a portion of the Minitab output. What can be concluded about the P-Value given this information? Difference = mu (Location A) - mu (Location B) Estimate for difference: 2.71582 95% CI for difference: (0.79550, 4.72251) T-Test of difference = 0 (vs not =): T-Value = 2.38 P-Value =???? a. Not enough information to determine P-Value b. P-Value is greater than 0.05 c. P-Value is less than 0.05 d. None of the above

4) Random samples of 12 customer service calls are selected from each site and the processing time noted. The average processing times are listed below (in minutes) Note: = .05 Site 1: 14.4 15.1 15.6 20.2 23.1 21.4 16.9 19.1 19.8 17.9 18.5 20.2 Site 2: 21.5 24.7 16.8 18.1 24.7 24.8 23.5 24.1 23.8 20.5 16.9 18.5 Use Tukeys Quick Test to determine which statement is correct. a. H0: a = b b. Ha: a b c. Ha: 1 2

5) Increasing the number of samples for our analysis will: a. Reduce our Power to detect defects b. Increase our Power to detect defects

6) What conclusions can be made about the Mean performance between four locations considering the Tukey Simultaneous Test listed below: a. The team can conclude there is difference in Means between TX and MN b. The team can conclude there is difference in Means between MN and OH c. The team can conclude there is difference in Means between OH and MA d. The team can conclude there is difference in Means between MA and MN

7) A quality Control Engineer would utilize Binomial Analysis of Means for situations where Proportion performance between three or more sites with equal sample sizes is investigated. True / False

8) The one-sample Wilcoxon test is a nonparametric counterpart to the parametric Two-sample t-test. True / False

9) A process improvement team is investigating the performance of three claim centers. Claim center number 3 appears to have a higher variance for claim examination time. Each center processes over 125,000 claims per day. A higher claim examination time variance could result in reduced customer satisfaction. What hypothesis testing tool should the team use? a. One-sample Wilcoxon b. BARTLETTS TEST c. Two-sample t-test. d. None of the above

10) The Kruskal - Wallis test is a nonparametric counterpart to what parametric Hypothesis Test? Ans) One way ANOVA test.
