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, 106 responded that they drive an American-made automobile. Determi majority of those with a valid driver's license drive an American-made automobile at the x = 0.05 level of significance. OC. Continuous D. Qualitative with two possible outcomes What type of hypothesis test is appropriate to conduct for this research? A. Hypothesis test on a population proportion OB. Hypothesis test on a population mean OC. Hypothesis test on a population standard deviation Determine the null and alternative hypotheses. Ho: P = 0.5 H₁: p > 0.5 (Type integers or decimals. Do not round.) Which distribution should be used for this hypothesis test? O A. 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, o is known, and the model conditions are satisfied. OC. The chi-square distribution because the parameter is o or o², 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.

Question
Expert Solution
Step 1: Proportion testing.
1.What type of variable is :
D. Qualitative with two possible outcomes
2.What type of hypothesis test is appropriate to conduct his research :
A. Hypothesis test on a population proportion
3.Determine the null and alternative hypothesis :
Normal distribution should be used for this hypothesis test
A.The normal distribution because the parameter is proportion p and the model conditions are satisfied.
Sample proportion =0.53
The test statistic is
Z=
= = 0.8474
p - value = P(Z>0.8474) = 0.1984
Since p-value > (=0.05), null hypothesis is accepted.
