Suppose that the proportion of students who used the Internet as their major resource for school in the past was 66%. A sample of 1000 students was taken and the number of students who used the Internet for their school during the past year was recorded. Let ��̂ be the proportion of students surveyed who used the Internet in the past year.

(A) What is the approximate distribution of ��̂ ?

(B) What is the probability that the sample proportion ��̂ exceeds 68%?

(C) What is the probability that the sample proportion lies between 64% and 68%?
