(c) State the conclusion for the test.Choose the correct answer below.A. Reject Ho because the P-value is less than the a = 0.05 level of significance.B. Do not reject H, because the P-value is less than the a = 0.05 level of significance.C. Reject H, because the P-value is greater than the a = 0.05 level of significance.D. Do not reject H, because the P-value is greater than the a = 0.05 level of significance.(d) State the conclusion in context of the problem.ThereV sufficient evidence at the a = 0.05 level of significance to conclude that more than half of all drivers drive a car made in this country. A simple random sample of size n = 200 drivers were asked if they drive a car manufactured in a certain country. Of the 200 drivers surveyed, 119 responded that theydid. Determine if more than half of all drivers drive a car made in this country at the a = 0.05 level of significance. Complete parts (a) through (d).(a) Determine the null and alternative hypotheses.Ho:0.5H4:0.5(b) Calculate the P-value.P-value =(Round to three decimal places as needed.)

It is given that Sample size n = 200 Number of drivers drive car made in the country, X = 119 Level…
