a-d 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, 103 responded that they drive an American-made automobile. Determine if a majorityof those with a valid driver's license drive an American-made automobile at the a = 0.05 level of significance....What type of variable is "drive an American-made automobile, or not"?A. DiscreteB. ContinuousC. Qualitative with more than two possible outcomesD. Qualitative with two possible outcomesWhat type of hypothesis test is appropriate to conduct for this research?O A. Hypothesis test on a population meanB. Hypothesis test on a population proportionC. Hypothesis test on a population standard deviationDetermine the null and alternative hypotheses.Ho:H4:(Type integers or decimals. Do not round.)Which distribution should be used for this hypothesis test?A. The chi-square distribution because the parameter is o or of, and the model conditions are satisfied.B. The Student's t-distribution because the parameter is the mean, o is not known, and the model conditions are satisfied.C. The normal distribution because the parameter is a proportion, p, and the model conditions are satisfied.D. The normal distribution because the parameter is the mean, o is known, and the model conditions are satisfied.

Given that n =200 ,x =103 Perform z test for one proportion
