The numbers of successes and the sample sizes for independent simple random samples from two populations are x 1equals32, n 1equals40, x 2equals10, n 2equals20. a. Use the two-proportions plus-four z-interval procedure to find an 95% confidence interval for the difference between the two populations proportions. b. Compare your result with the result of a two-proportion z-interval procedure, if finding such a confidence interval is appropriate.
Two samples are taken with the following sample means, sizes, and standard deviations ¯ x1 x¯1 = 31 ¯ x2 x¯2 = 28 n1 n1 = 70 n2 n2 = 46 s1 s1 = 4 s2 s2 = 2 We want to estimate the difference in population means using a 89% confidence level. What distribution does this require? t, df = 108 z NOTE: The more accurate df formula, used above, is: df= ( s 2 1 n1 + s...
