Two hundred and seventy eight out of a random sample of 500 U.S. males in the southeastern (SE) states drive a pickup truck. One hundred and twenty one out of a random sample of 248 U.S. males in the northeastern (NE) states drive a pickup truck. The claim is that the proportion of U.S. males driving a pickup truck is equal in these two regions. The Excel summary results are shown below. Using this output, specify whether each of the following conclusions is correct or incorrect.
A. At the 10% significance level, we reject the claim that the proportion of U.S. males driving a pickup truck in the southeastern states is equal to the northeastern states.
B. At the 1% significance level, we reject the claim that the proportion of U.S. males driving a pickup truck in the southeastern states is equal to the northeastern states.
C. At the 5% significance level, we reject the claim that the proportion of U.S. males driving a pickup truck in the southeastern states is equal to the northeastern states.
D. At the 2.5% significance level, we CANNOT reject the claim that the proportion of U.S. males driving a pickup truck in the southeastern states is equal to the northeastern states.
A. At the 10% significance level, we reject the claim that the proportion of U.S. males driving a pickup truck in the southeastern states is equal to the northeastern states.
Since the p-value (0.0788) < 0.10, we reject the claim at the 10% significance level. Since the p-value (0.0788) > 0.025, we cannot reject the claim at the 2.5% significance level. The remaining answer choices are incorrect.
