The accompanying data are taken from three different populations known to be normally distributed, with equal population variances based on independent simple random samples. Complete parts (a) through (c). (a) Test the hypothesis that each sample comes from a population with the same mean at the α= 0.05 level of significa
P. value = (Round to three decimal places as needed.)
Choose the correct conclusion below.
A. Reject the null hypothesis.
B. Do not reject the null hypothesis.
(b) If you rejected the null hypothesis in part (a), use Tukey's test to determine which pairwise means differ using a fa Find the Tukey 95% simultaneous confidence intervals for all pairwise comparisons. Select the correct coice below o
A. The interval for the pairwise comparison μ2-u1 is:
The interval for the pairwise comparison μ3-u, is:
The interval for the pairwise comparison u3- H2 is: (Round to two decimal places as needed.)
B. The null hypothesis was not rejected.
