A simple random sample of size n = 200 drivers with a valid driver's license is asked if they drive an American-made automobile. Of the 200 drivers surveyed, 118 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. Determine the null and alternative hypotheses. Họ: H1: (Type integers or decimals. Do not round.) Which distribution should be used for this hypothesis test? O A. The Student's t-distribution because the parameter is the mean, o is not known, and the model conditions are satisfied. O B. The normal distribution because the parameter is a proportion, p, and the model conditions are satisfied. O C. The normal distribution because the parameter is the mean, o is known, and the model conditions are satisfied. O D. The chi-square distribution because the parameter is o or o?, and the model conditions are satisfied.
