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, 122 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"? A. Qualitative with two possible outcomes O B. Discrete O C. Continuous O D. Qualitative with more than two possible outcomes What type of hypothesis test is appropriate to conduct for this research? O A. Hypothesis test on a population standard deviation B. Hypothesis test on a population proportion C. Hypothesis test on a population mean Determine the null and alternative hypotheses. Ho: p = 0.5 H: p (Type integers or decimals. Do not round.) 0.5 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. OB. The normal distribution because the parameter is the mean, o is known, and the model conditions are satisfied. C. The normal distribution because the parameter is a proportion, p, and the model conditions are satisfied. O D. The Student's t-distribution because the parameter is the mean, o is not known, and the model conditions are satisfied. Calculate the test statistic, Test statistic (Round to two decimal places as needed.)
