What critical value t∗ from Table D should be used to construct a 95% confidence interval for μ (the population mean) when n = 15 (if applicable, please round your answer to at least 3 decimal places)? You are given only the following information for a hypothesis test of H0: μ=10versusHa: μ̸=10: x ̄ = 12.2 P-value = 0.08 Suppose, based on prior knowledge, the alternative Ha: μ < 10 was actually more appropriate. What is the P-value for the...
