(b) The approximate probability that the average test score exceeds 65 in the class of size 36 is (B). Find the value of B.Answer:(c) Which probability is larger?Select one:None. They are equal.That in the class of size 36.that in the class of size 100. Let us suppose that a particular lecturer manages, with probability 1, to develop exams that have mean 60 and standarddeviation 12. The lecturer is teaching two classes, one of size 100 and the other one of size 36, and is about to give an exam toboth classes. We treat all students as being independent. Give your answers below in three decimal places.(a) The approximate probability that the average test score in the class of size 100 exceeds 65 is (a), where is the cumulativedistribution function of a standard normal random variable. Find the value of a.Answer:
