Unformatted text preview: (a) What is the probability that a random sample of 36 of these resistors will have a combined resistance of more than 1458 ohms? (b) Your answer in part (a) is merely an approximation. What additional assumption is needed to provide an exact probability statement? (c) Which theorem indicates that our result in part (a) is reasonable, even without the additional assumption in part (b)? STA 301-B, Spring 2008 Homework 8 Page 3 of 3 Question 3 A random sample of size 100 is drawn from a normal distribution with mean 150 = and standard deviation 15 = . Find the probability that (a) the first member of the sample takes a value between 148 and 152. (b) the sample mean takes a value between 148 and 152....
