Question

A student believes that the average grade on the final examination in statistics is at least 85. She plans on taking a sample to test her belief. The correct set of hypotheses is _____. A) H₀: μ < 85 H_a: μ ≥ 85 B) H₀: μ ≤ 85 H_a: μ > 85 C) H₀: μ ≥ 85 H_a: μ < 85 D) H₀: μ > 85 H_a: μ ≤ 85

Quizplus · Accepted Answer

The null hypothesis should be that the average grade on the final examination in statistics is less than or equal to 85 (μ ≤ 85), and the alternative hypothesis should be that the average grade is greater than 85 (μ > 85). Therefore, option C is the correct set of hypotheses.
