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.
State the null and alternative hypotheses.
Myt = Sl = WH = N :°H O
Ha: HN * HM * Hs# Hw
O Ho: Not all the population means are equal.
Ha: "N = HM = Hs = Hw
O Ho: HN * HM * Hs# Hw
Myi = Sri = Wi = Ni :°H
O Ho: HN = HM = "s = Hw
H.: Not all the population means are equal.
O Ho: At least two of the population means are equal.
H.: At least two of the population means are different.
Find the value of the test statistic. (Round your answer to two decimal places.)
Find the p-value. (Round your answer to three decimal places.)
p-value =
State your conclusion.
O 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.
