Extracted text: For the cases below: a) determine the critical value, b) draw the comparison distribution with the rejection region(s) shaded, and c) calculate the appropriate test statistic. When using the t-distribution table, if your critical value is between two values for the degrees of freedom, use the lower/smaller value. If your degrees of freedom are larger than the values given in the table, use the very last value in the appropriate column. Case 1: n = 48, = 175, s = 12, HA: µ 180 , = .05 Case 2: n = 48, = 175, HẠ: µ 180, = 10, = .05 Case 3: n = 25, = 175, S 12, HA: µ 180, = .01 Case 4: n %3D 25, %3D 175, Н.: и 180, 3 10, %3 .01 Case 5: n %3D 1, х%3D 175, На: и 180, — 10, — .05 ||
