Note that probabilities in questions involving the normal distribution were computed using software. If
you used the standard normal tables, your answer may differ slightly.
1. Let X denote the unrounded measured voltage (

HW 5 Solutions
Exercise 1.
Solution. (a) Let X be the number of stars per 16 cubic light years; then X is a Poisson
random variabile with rate 1. Consequently,
P (X 2) = 1 P (X = 0) P (X = 1) = 1 e1 1 e1 = 0.264.
