If, in a sample of n=25 selected from a normal population, X=59 and S=10,what is your statistical decision if the level of significance,α is 0.10, the null hypothesis, H0, is μ=50, and the alternative hypothesis, H1, is μ≠50? a. Determine the critical value(s). The critical value(s) is(are) ____________. (Round to four decimal places as needed. Use a comma to separate answers as needed.) b. Determine the test statistic, tSTAT. tSTAT=______________ (Round to four decimal places as needed.) c. State your statistical decision. Choose the correct answer below. A. The test rejects the null hypothesis. The data provide sufficient evidence to conclude that the mean differs from μ=50. B. The test does not reject the null hypothesis. The data provide sufficient evidence to conclude that the mean differs from μ=50. C. The test does not reject the null hypothesis. The data does not provide sufficient evidence to conclude that the mean differs fromμ=50. D. The test rejects the null hypothesis. The data does not provide sufficient evidence to conclude that the mean differs from μ=50.
