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.
O B. The chi-square distribution because the parameter is a or o, and the model conditions are satisfied.
O C. The normal distribution because the parameter is the mean, o is known, and the model conditions are satisfied.
D. The normal distribution because the parameter is a proportion, p, and the model conditions are satisfied.
Calculate the test statistic.
