Which distribution should be used for this hypothesis test? O A. The Student's t-distribution because the parameter is the mean, o is not known, and the model conditions are satisfied. B. 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 o?, and the model conditions are satisfied. O D. The normal distribution because the parameter is a proportion, p, 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.
