Question

Use technology and a t-test to test the claim about the population mean ? at the given level of significance ? using the given sample statistics. Assume the population is normally distributed. Claim: ? > 77; ? = 0.10 Sample statistics: x? = 78.2, s = 3.6, n = 26 What are the null and alternative hypotheses? Choose the correct answer below. A. H?: ? = 77 H?: ? ? 77 B. H?: ? ? 77 H?: ? < 77 C. H?: ? ? 77 H?: ? > 77 D. H?: ? ? 77 H?: ? = 77 What is the value of the standardized test statistic? The standardized test statistic is . (Round to two decimal places as needed.)
