- What is the P-Value and Test Statistic of this problem. The dean of a university estimates that the mean number of classroom hours per week for full-time faculty is 11.0. As a member of the student council, you want to test this claim. A random sample of the number of classroom hours for eight full-time faculty for one week is shown in the table below. At α=0.01, can you reject the dean's claim? Complete parts (a) through (d) below.

P-value=____(Round to three decimal places as needed.)arrow_forwardYou are conducting a significance test of H0: μ = 7.2 against Ha: μ < 7.2. After checking the conditions are met from a simple random sample of 25 observations, you obtain t = - 1.45. Based on this result, describe the p-value. Group of answer choices The p-value falls between 0.05 and 0.1. The p-value falls between 0.025 and 0.05. The p-value falls between 0.02 and 0.025. The p-value falls between 0.005 and 0.01. The p-value is less than 0.005.arrow_forward

A consumer group feels that the company is overestimating the mean miles per gallon and asks the Consumer Protection Agency to investigate. The CPA plans to take a random sample of 30 cars of this model, find the mean miles per gallon for these cars, and conduct a test to determine whether the mean is significantly less than 24 mpg.
