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 > .75 Ha: p ≤ .75 B) H₀: p < .75 Ha: p ≥ .75 C) H₀: p ≥ .75 Ha: p < .75 D) H₀: p ≤ .75 Ha: p > .75

Quizplus · Accepted Answer

The null hypothesis should state that the proportion of tourists visiting Rock City is equal to or less than the original proportion (0.75), and the alternative hypothesis should state that the proportion is now greater than 0.75 (since the promotional campaign was aimed at increasing the proportion). Therefore, the correct set of hypotheses is H₀: p ≤ .75 Ha: p > .75, which is represented by choice D.
