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, 116 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. What type of variable is "drive an American-made automobile, or not"? OA. Qualitative with two possible outcomes B. Continuous OC. Qualitative with more than two possible outcomes OD. Discrete What type of hypothesis test is appropriate to conduct for this research? OA. Hypothesis test on a population mean B. Hypothesis test on a population standard deviation OC. Hypothesis test on a population proportion Determine the null and alternative hypotheses. Ho: H: (Type integers or decimals. Do not round.) Which distribution should be used for this hypothesis test? OA. The normal distribution because the parameter is a proportion, p, and the model conditions are satisfied. OB. The normal distribution because the parameter is the mean, a is known, and the model conditions are satisfied. Click to select your answer(s).

Of the 200 drivers surveyed, 116 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 x = 0.05 level of significance. Ho: H: (Type integers or decimals. Do not round.) Which distribution should be used for this hypothesis test? OA. The normal distribution because the parameter is a proportion, p, and the model conditions are satisfied. B. The normal distribution because the parameter is the mean, a is known, and the model conditions are satisfied. C. The chi-square distribution because the parameter is a or o, and the model conditions are satisfied. OD. The Student's t-distribution because the parameter is the mean, a is not 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= (Round to three decimal places as needed.) State the conclusion for the test. Ho- There sufficient evidence at the a= 0.05 level of significance to conclude that drivers with a valid driver's license drive an American-made automobile. Click to select your answer(s). more than half fewer than half different than half half of all
