A sample mean, sample size, and population standard deviation are given. Use the one-mean z-test to perform the required hypothesis test at the given significance level. Use the critical value approach. (A) Calculate the test statistic (clearly label it as either z or t as needed); (2) Embed a photo of a manual sketch of the distribution with the critical region(s) shaded and the test-statistic clearly labeled; (3) Determine whether to reject or fail to reject H0, (4) Write a conclusion based on the rejection or failure to reject H0. All math must be typeset appropriately using the Rich Text Editor. You must embed the sketch of the critical region within the Rich Text Editor adhering to the Photo Upload Guidelines. = 25, n = 40, σ = 1.5, H0: μ = 22 Ha: μ ≠ 22 **claim** α = 0.05
