23) Should each of the following use a paired or unpaired (two-sample) t-test? a) If we collect blood glucose levels of cloned mice (i.e., the mice are genetically identical) that are fed either a low-carb or high-carb diet. b) If we collect blood glucose levels of individuals before and after they eat cake and ice cream. c) If we collect blood glucose levels from a group of people that eat chicken and spinach and then blood glucose levels from a second group of people that eat cake and ice cream. 24) The paired t-test is essentially the same as a one-sample t-test of the set of differences with a hypothesized mean of zero for the differences. A. True B. False 25) Can we appropriately conduct a two-sample t-test on the following data - why or why not? Sample 1: mean = 6.4, SD = 2.5 Sample 2: mean = 3.2, SD = 0.7 Sample 1: Sample 2: 1 0 1 2 3 4 5 6 7 8 9 10 11 01 2 3 4 5 26) Which of the following is not true for a two-sample f-test? [Check all that apply]: A. The sampling unit = the pair B. It compares the mean of two groups C. The null hypothesis states that the mean values will be equal to 0 D. The degrees of freedom is equal to the sum of the sample sizes minus 2 27) Which test should we conduct if the variances between two samples are different according to Levene's test for homogeneity of variances? A. Binomial distribution B. Fisher's Exact Test C. Two-sample f-test D. Welch's t-test
