An employment information service claims the mean annual pay for full-time male workers over age 25 without a high school diploma is $22,300. The annual pay for a random sample of 10 full-time male workers over age 25 without a high school diploma is listed. At α=0.01, test the claim that the mean salary is $22,300. Assume the population is normally distributed. 20,655 21,137 22,354 21,395 22,970 16,912 19,155 23,193 24,188 26,290 (b) Find the critical value(s) and identify the rejection region(s). What is(are) the critical value(s), t0? t0= (Use a comma to separate answers as needed. Round to three decimal places as needed.) (c) Find the standardized test statistic. t= (Round to two decimal places as needed.)
