Suppose That You Wish to Compare the Mean Home Values

Multiple Choice

Suppose that you wish to compare the mean home values from three different regions. The Bonferroni-corrected intervals for all three comparisons are shown in the table. Assume an overall confidence level of 95%, that is, an individual confidence level of 98.33%. Choose the statement that is true about the differences among the three means. If none of the statements is true, then choose (d) . North East - North Central ($52,485, $78,875) North East - Far West (-$8,724, $14,547) Far West - North Central ($50,093, $75,443)

A) The interval comparing North East to North Central does not capture 0; there is no significant difference in the mean home values between the North East and the North Central regions.
B) The interval comparing Far West to North Central does not capture 0; there is no significant difference in the mean home values between the Far West and the North Central regions.
C) The interval comparing North East to Far West captures 0; there is no significant difference in mean home values between the North East and the Far West regions.
D) None of the statements is true.
