A survey at the University found that 22 % of students use Reading Week primarily for academic work. Suppose you randomly select 32 Did you use Reading Week primarily for academic work? (a) What is the probability that 13 of these students respond YES? P(X = 13) = (use five decimals in your answer) (b) What is the probability that between 15 and 19 of these P(15≤ X ≤19)= =0 (use five decimals in your answer) students respond YES? (c) How many of the 32 births would you expect to respond YES? Find the standard deviation as well. E(X) = x = (use two decimals in your answer) SD(X) = ox= (use two decimals in your answer) (d) What is the probability that more than 11 of these hese P(X > 11) (use five decimals in your answer) students will respond YES? students and ask each the following question:
