Ho: μ = 22 - H₁:22 x = 25.1, n = 59, σ = 8.45, α = .01 a. Use the data given to test the following hypotheses. (Round your answer to 2 decimal places, e.g. 15.25.) The value of the test statistic is and we b. Use the p-value to reach a statistical conclusion. (Round your answer to 4 decimal places, e.g. 0.1254.)
