# Question

A random sample of size 1000 has x = 104. The significance level α is set at 0.05. The P-value for testing H0: μ = 100 against Ha: μ ≠ 100 is 0.057. Explain what is incorrect about each of the following interpretations of this P-value, and provide a proper interpretation.

a. The probability that the null hypothesis is correct equals 0.057.

b. The probability that x = 104 if H0 is true equals 0.057.

c. If in fact μ ≠ 100 so H0 is false, the probability equals 0.057 that the data would show at least as much evidence against H0 as the observed data.

d. The probability of a Type I error equals 0.057.

e. We can accept H0 at the α = 0.05 level.

f. We can reject H0 at the α = 0.05 level.

One interpretation for the P-value is that it is the smallest value for the significance level α for which we can reject H0. Illustrate using the P-value of 0.057 from the previous exercise.
