1 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, 104 responded that they drive anAmerican-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 more than two possible outcomesB. DiscreteC. ContinuousD. Qualitative with two possible outcomesWhat type of hypothesis test is appropriate to conduct for this research?A. Hypothesis test on a population proportionB. Hypothesis test on a population standard deviationC. Hypothesis test on a population mean

Statistical hypothesis testing is an important method in inferential statistics. It is used to test the hypothesis about the population parameters. Statistical tests are used to calculate the test statistic and p-value. This test statistic and p-value will eventually be used to make decision on the rejection of null hypothesis.i) The question asked is a yes or no question. Qualitative variables are non numeric variables. Here the responses are non numeric. So this is a qualitative variable with 2 possible outcomes. So option D is correct. Since there are only 2 possible outcomes, option A is wrong. Discrete variables will have numeric outcomes. Here the responses are non numeric and hence option B is wrong. Continuous variables will have numeric outcomes. Here the responses are non numeric and hence option C is wrong.ii) Here the parameter or interest is the proportion of drivers who drive a particular type of automobile. So hypothesis test on a population proportion is the required hypothesis test and hence option A is the correct option. The variable is non numeric here and hence standard deviation is not relevant. So option B is wrong. The variable is non numeric here and hence mean is not relevant. So option C is wrong.
