Question

Consider the following null and alternative hypotheses: H0 : p = 0.84 versus H1 : p ? 0.84. A random sample of 500 observations taken from this population produced a sample proportion of 0.86. 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 = zcritical left = zcritical right = We the null hypothesis. b. What is the probability of making a Type I error in part a? P(Type I error) = c. Calculate the p-value for the test. Based on this p-value, would you reject the null hypothesis if ? = 0.02? What if ? = 0.04? Round your answer for the p-value to four decimal places. p-value =
