Question: Consider the following null and alternative hypotheses: H0: p = .44 versus H1: p < .44 A random sample of 450 observations taken from this

Consider the following null and alternative hypotheses:
H0: p = .44 versus H1: p < .44
A random sample of 450 observations taken from this population produced a sample proportion of .39.
a. If this test is made at a 2% significance level, would you reject the null hypothesis? Use the critical-value approach.
b. What is the probability of making a Type I error in part a?
c. Calculate the p-value for the test. Based on this p-value, would you reject the null hypothesis if α = .01? What if α = .025?
