Question

The academic planner of a university thinks that at least 35% of the entire student body attends summer school. The correct set of hypotheses to test his belief is A) H₀: p < .35 H_a: p .35. B) H₀: p .35 H_a: p > .35. C) H₀: p .35 H_a: p < .35. D) H₀: p > .35 H_a: p .35.

Quizplus · Accepted Answer

The null hypothesis (H0) should be the belief that the planner wants to test, which is that at least 35% of the entire student body attends summer school. Therefore, the correct set of hypotheses should be:
H0: p >= .35
Ha: p < .35
Choice C has the correct format for the hypotheses with a null hypothesis greater than or equal to 0.35 and an alternative hypothesis less than 0.35. The other choices have either incorrect symbols or incorrect inequality directions for the null or alternative hypotheses.
