Consider the hypotheses shown below. Given that x overbare=57, sigma=11, n=33, alph=0.05, complete parts a and b. Upper H 0: muless than or equals55 Upper H 1: mugreater than55 a. What conclusion should be drawn? b. Determine the p-value for this test. a. The z-test statistic is ? (Round to two decimal places as needed.) The critical z-score(s) is(are) ? (Round to two decimal places as needed. Use a comma to separate answers as needed.) Because the test statistic does not fall within the critical values, reject or accept the null hypothesis?
