Question: Repeat Exercise 7 45 but without using the correction for continuity
Repeat Exercise 7.45, but without using the correction for continuity (i.e., the discrete random variable, x, is not replaced by the interval x – 0.5 to x + 0.5). Does your answer differ appreciably from that obtained in Exercise 7.45? If not, comment on the need for using the correction for continuity when x can take on a large number of possible values.
