In each of Exercises the null hypothesis is H0:µ1 = µ2 and the alternative hypothesis is as specified. We have provided data from independent simple random samples from the two populations under consideration.

In each of Exercises we have provided summary statistics for independent simple random samples from two populations. In each case, use the pooled t-test and the pooled t-interval procedure to conduct the required hypothesis test and obtain the specified confidence interval. x1 = 10, s1 = 2.1, n1 = 15, x2 = 12, s2 = 2.3, n2= 15 a. Two-tailed test, a = 0.05 b. 95% confidence interval
In each of Exercises, we have given the P-value for a hypothesis test. For each exercise, refer to Table to determine the strength of the evidence against the null hypothesis. P-value Evidence against H0 P > 0.10 Weak or none 0.05 < P ≤ 0.10 Moderate 0.01 < P ≤ 0.05 Strong P ≤ 0.01 Very strong P = 0.086
In each of Exercises, we have provided a null hypothesis and alternative hypothesis and a sample from the population under consideration. In each case, use theWilcoxon signed-rank test to perform the required hypothesis test at the 10% significance level. H0: µ = 10, Ha: µ<10 7 6 5 12 15 14 13 4
In a completely randomized experimental design, three brands of paper towels were tested for their ability to absorb water. Equal-size towels were used, with four sections of towels tested per brand.
