A two-tailed hypothesis test for H₀: μ = 15 at α = .10 is analogous to asking if a 90 percent confidence interval for μ contains 15.

Question

Quizplus · Accepted Answer

A two-tailed hypothesis test at α = .10 means we are looking for the probability of observing a sample mean as extreme or more extreme than the one we have, assuming the null hypothesis that the population mean is 15. This is equivalent to constructing a 90% confidence interval for the population mean and seeing if it includes the value of 15. Therefore, the statement is true.
