A simple random sample of sizen=200 drivers with a valid driver's license is asked if they drive an American-made automobile. Of the 200 drivers surveyed, 103 responded that they drive an American-made automobile. Determine if a majority of those with a valid driver's license drive an American-made automobile at the a= 0.05 level of significance. O A. Hypothesis test on a population mean O B. Hypothesis test on a population proportion O C. Hypothesis test on a population standard deviation Determine the null and alternative hypotheses. Họ: H,: (Type integers or decimals. Do not round.) Which distribution should be used for this hypothesis test? O A The chi-square distribution because the parameter is o or o?, and the model conditions are satisfied. O B. The Student's t-distribution because the parameter is the mean, o is not known, and the model conditions are satisfied. OC. The normal distribution because the parameter is a proportion, p, and the model conditions are satisfied. O D. The normal distribution because the parameter is the mean, o is known, and the model conditions are satisfied. Calculate the test statistic. Test statistic = (Round to two decimal places as needed.) Calculate the P-value. P-value =O (Round to three decimal places as needed.) State the conclusion for the test. V Ho. There V sufficient evidence at the a = 0.05 level of significance to conclude that V of all drivers with a valid driver's license drive an American-made automobile.
