Question

ssume that z is the test statistic.

(a) H0: μ = 22.5, Ha: μ > 22.5; x = 24.8, σ = 7.3, n = 37

(i) Calculate the test statistic z. (Round your answer to two decimal places.)

(ii) Calculate the p-value. (Round your answer to four decimal places.)

(b) H0: μ = 200, Ha: μ < 200; x = 192.1, σ = 34, n = 32

(i) Calculate the test statistic z. (Round your answer to two decimal places.)

(ii) Calculate the p-value. (Round your answer to four decimal places.)

(c) H0: μ = 12.4, Ha: μ ≠ 12.4; x = 10.6, σ = 5.4, n = 28

(i) Calculate the test statistic z. (Round your answer to two decimal places.)

(ii) Calculate the p-value. (Round your answer to four decimal places.)
