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 H_a: p $\le$ 0.75 B)H₀: p < 0.75 H_a: p $\ge$ 0.75 C)H₀: p $\ge$ 0.75 H_a: p < 0.75 D)H₀: p $\le$ 0.75 H_a: p > 0.75

Quizplus · Accepted Answer

The null hypothesis (H0) should reflect the status quo or no effect, which is that the proportion is less than or equal to 0.75. The alternative hypothesis (Ha) should reflect the effect of the campaign, which is an increase, so p > 0.75.
