A student performs a test of H0: p = 0.4 versus Ha: p ≠ 0.4 and gets a p-value of 0.03. The student writes: "Because the p-value is not equal to 0.4, we reject the null hypothesis." What is wrong with the student's conclusion?
a. The p-value should be compared with a significance level such as α = 0.05, not the hypothesized value of p.
b. The p-value should be compared with the mean, not the hypothesized value of p.
c. The p-value should be compared with the standard deviation, not the hypothesized value of p.
d. The student should have stated the data prove Ha is true.
e. The student should have stated the data prove H0 is true.
