A random sample of 500 adult residents of Maricopa County indicated that 385 were in favor of increasing the highway speed limit to 75 mph. Is it reasonable to conclude that the proportion of the adult residents of Maricopa County that are in favor of increasing the highway speed limit to 75 mph is greater than 0.60? Use α = 0.05 to test the hypothesis. Answer the following Questions: a. What is the parameter of interest? b. State the null hypothesis c. State the alternative hypothesis d. Calculate the test statistic value. e. What is the critical (rejection) region for H0? f. Write conclusion. g. What is the P-value?

Is it reasonable to conclude that the proportion of the adult residents of Maricopa County that are in favor of increasing the highway speed limit to 75 mph is greater than 0.60? Use α = 0.05 to test the hypothesis. Answer the following questions: What is the parameter of interest? State the null hypothesis. State the alternative hypothesis. Calculate the test statistic value. What is the critical (rejection) region for Ho? Write the conclusion. What is the P-value?
10.6.4 Part 1 A random sample of 500 adult residents of Maricopa County found that 367 were in favor of increasing the highway speed limit to 75 mph, while another sample of 400 adult residents of Pima County found that 285 were in favor of the increased speed limit. Do these data indicate that there is a difference in the support for in increasing the speed limit between the residents of the two counties? Use α = 0.05. (a) Test the hypothesis H0: p1 = p2 versus H1: p1 ≠p2. What is z0? Round your answer to two decimal places (e.g. 98.76). z0 = (b) Is it reasonable to conclude that there is a difference in the support for increasing the speed limit between the residents of the two counties? the absolute tolerance is +/-0.01
