Question

A meteorologist stated that the average temperature during July in Chattanooga was 80 degrees. A sample of July temperatures over a 32-year period was taken. The correct set of hypotheses is _____. A) H₀: μ < 80 H_a: μ ≤ 80 B) H₀: μ ≤ 80 H_a: μ > 80 C) H₀: μ ≠ 80 H_a: μ = 80 D) H₀: μ = 80 H_a: μ ≠ 80

Quizplus · Accepted Answer

The null hypothesis (H0) should state that the average temperature is equal to the claimed value, 80 degrees, while the alternative hypothesis (Ha) should state that it is not equal to 80 degrees.
