Suppose a university advertises that its average class size is 34 or less. a student organization is concerned that budget cuts have led to increased class sizes and would like to test this claim. a random sample of 43 classes was selected, and the average class size was found to be 36.4 students. assume that the standard deviation for class size at the college is 7 students. using alpha equals 0.10, complete parts a and b below. a. does the student organization have enough evidence to refute the college's claim? determine the null and alternative hypotheses. h0: μ (greater than or equals≥ less than or equals≤ greater than> not equals≠ equals= less than< )h1: μ (equals= less than or equals≤ greater than or equals≥ less than< greater than> not equals≠)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, is greater than the critical value, is less than the critical value, falls within the critical not reject, reject) the null hypothesis. enter your answer in the edit fields
