Which set of characteristics will produce the smallest standard error?  (Looking at the formula will help make this clear.)       A large sample size and a small sample variance       A small sample size and a large sample variance       A small sample size and a small sample variance       A large sample size and a large sample variance

Diet Regular Data on the weights (Ib) of the contents of cans of diet soda versus the contents of cans of the regular version of the soda is summarized to the right. Assume that the two samples are independent simple random samples selected from normally distributed populations, and do not assume that the population standard deviations are equal. Complete parts (a) and (b) below. Use a 0.05 significance level for both parts. P2 39 39 0.79824 lb 0.00435 lb 0.81781 lb 0.00756 lb 康 ※ a. Test the claim that the contents of cans of diet soda have weights with a mean that is less than the mean for the regular soda. What are the null and alternative hypotheses? O B. Ho H1 = H2 H H2 O A. Ho H H2 O D. Ho: H1 H2 H #2 O C. Ho H H2 The test statistic, t, is (Round to two decimal places as needed.) The P-value is .(Round to three decimal places as needed.) State the conclusion for the test. O A. Fail to reject the null hypothesis. There is sufficient evidence to support the claim that the cans of…

8. Assumptions underlying the independent-measures ANOVA Which of the following are assumptions underlying independent-measures analysis of variance? Check all that apply.   The populations from which the samples are taken follow an F distribution.   The observations are independent of one another.   Each of the populations of scores from which the samples are drawn has the same variance.   Each of the populations of scores from which the samples are drawn is normally distributed.
