Use ? = 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.
1)State the null and alternative hypotheses.
A) H0: At least two of the population means are equal.
Ha: At least two of the population means are different
Ha: At least two of the population means are different
B)H0: Not all the population means are equal.
Ha: ?N = ?M = ?S = ?W
Ha: ?N = ?M = ?S = ?W
C) H0: ?N ≠ ?M ≠ ?S ≠ ?W
Ha: ?N = ?M = ?S = ?W
Ha: ?N = ?M = ?S = ?W
D) H0: ?N = ?M = ?S = ?W
Ha: Not all the population means are equal
Ha: Not all the population means are equal
E) .H0: ?N = ?M = ?S = ?W
Ha: ?N ≠ ?M ≠ ?S ≠ ?W
Ha: ?N ≠ ?M ≠ ?S ≠ ?W
#2) Find the value of the test statistic (round your answer to two decimal places), and the p-value (round your answer to three decimal places)
#3)State your conclusion.
A) Do not reject H0. 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.
B)Reject H0. 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.
C) Do not reject H0. 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 H0. 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.
