Question

Determine the P-value in a hypothesis test for a population mean with H₀: µ = hypothesized value and Ha: µ > hypothesized value. A) area to the right of the calculated t under the t curve with df = n − 2 B) area to the left of the calculated t under the t curve with df = n − 1 C) area to the right of the calculated t under the t curve with df = n − 1 D) area to the left of the calculated t under the t curve with df = n − 2 E) area to the right of the calculated t under the t curve with df = n

Quizplus · Accepted Answer

When testing a hypothesis for a population mean with a one-tailed alternative hypothesis (in this case, µ > hypothesized value), the p-value is the area to the right of the calculated t statistic under the t distribution with df = n - 1. Therefore, choice C is the correct answer.
