At an alpha level of .05, test the null hypothesis against the alternative that there is no difference in mean height of randomly selected statistics students to the population norm (H = 63, o = 2.5). Using this information, the correct format for the null and alternative hypotheses for step 1 in the seven- step process would be: O Ho: H = 63 Ha: H # 63 O Ho: H # 63 Ha: H = 63 O Ho: H = 70 Ha: H # 70 O Ho: H = .05 Ha: H # .05
