Question:
The statistical program MINITAB will calculate \(t\) tests. With the nanopillar height data in \(\mathrm{C} 1\),
You must compare your preselected \(\alpha\) with the printed \(P\)-value in order to obtain the conclusion of your test. To perform a \(Z\) test, you need to find the \(P\)-value corresponding to the value 1.07 for the test statistic.
Here, with the two-sided alternative, we cannot reject \(H_{0}: \mu=300 \mathrm{~nm}\) unless we take the significance level almost as large as 0.30 .
(a) Test \(H_{0}: \mu=295\) with \(\alpha=0.05\).
(b) Test \(H_{0}: \mu=16.0\) for the speed of light data in Exercise 2.66 with \(\alpha=0.05\).
