Question

In the past, 75% of the tourists who visited Chattanooga went to see Rock City. The management of Rock City recently undertook an extensive promotional campaign. They are interested in determining whether the promotional campaign actually increased the proportion of tourists visiting Rock City. The correct set of hypotheses is A) H0: P > 0.75 Ha: P ≤ 0.75 B) H0: P < 0.75 Ha: P ≥ 0.75 C) H0: P ≥ 0.75 Ha: P < 0.75 D) H0: P ≤ 0.75 Ha: P > 0.75

Quizplus · Accepted Answer

The null hypothesis (H0) is that the proportion of tourists visiting Rock City is equal to or less than the previous proportion of 75%. The alternative hypothesis (Ha) is that the proportion of tourists visiting Rock City has increased, so it is greater than 75%. Therefore, the correct set of hypotheses is H0: P ≤ 0.75 Ha: P > 0.75. The other options either have the wrong direction for the alternative hypothesis or the wrong equality sign for the null hypothesis.
