Use a = 0.05, to test whether the mean percentage of 17-to 24-year-olds who are attending college is the same for the four geographic regions. Circle the null and alternative hypotheses below (a) Ho: HN HM = US = W Ha: Not all the population means are equal. (b) Ho: UN UM # S # W Ha: UN UM = US = w (c) Ho: UN = M = s = w Ha: UN UMHS # HW (d) Ho: At least two of the population means are equal. Ha: At least two of the population means are different. (e) Ho: Not all the population means are equal. Ha: UN UM = US = w Test statistic = (Round to two decimal places) p-value = Select One Below (Round to three decimal places) (a)Do not reject Ho. There is sufficient evidence to conclude that the percentage of 17- to 24-year-olds who are attending college is not the same for the four geographic regions. (b)Do not reject Ho. There is not sufficient evidence to conclude that the percentage of 17- to 24-year-olds who are attending college is not the same for the four geographic regions. (c)Reject Ho. There is sufficient evidence to conclude that the percentage of 17-to 24-year-olds who are attending college is not the same for the four geographic regions. (d)Reject Ho. There is not sufficient evidence to conclude that the percentage of 17- to 24-year-olds who are attending college is not the same for the four geographic regions.
