We have independent random samples from two populations. Compute the 95% CI for the difference between the two population means. Use df = 52 , if needed.

Sample 1: n = 30 , X-bar = 40 , σ 2 = 50

Sample 2: n = 40 , X-bar = 80 , σ 2 = 30

Independent random samples, each containing 60 observations, were selected from two populations. The samples from populations 1 and 2 produced 37 and 30 successes, respectively. Test H0:(p1−p2)=0 against Ha:(p1−p2)≠0. Use α=0.05. (a) The test statistic is   (b) The P-value is (c) The final conclusion is A. We can reject the null hypothesis that (p1−p2)=0 and conclude that (p1−p2)≠0. B. There is not sufficient evidence to reject the null hypothesis that (p1−p2)=0.

Assume that the two samples are independent simple random samples selected from normally distributed populations. Do not assume that the population standard deviations are equal. Refer to the accompanying data set. Use a 0.01 significance level to test the claim that the sample of home voltages and the sample of generator voltages are from populations with the same mean. If there is a statistically significant difference, does that difference have practical significance? Day    Home (volts)   Generator (volts) 1   123.7  ...
