Consider the following null and alternative hypotheses:Ho: p = 0.84 versus H1: p + 0.84.A random sample of 575 observations taken from this population produced a sample proportion of 0.90.a. If this test is made at a 10% significance level, would you reject the null hypothesis? Use the critical-value approach.Round your answer for z to two decimal places.Zobserved =iZcritical left =iZcritical right =Wethe null hypothesis.b. What is the probability of making a Type l error in part a?P(Type I error) = ic. Calculate the p-value for the test. Based on this p-value, would you reject the null hypothesis if a = 0.02?
