Problem 28E

Let ? ?be a standard normal random variable and calculate the following probabilities, drawing pictures wherever appropriate.

Step-by-Step Solution:

Answer : Step 1 of 10 : Let Z be a standard normal random variable The claim is to calculate the probabilities a) We have to find the probability values for P(0 Z 2.17) Let, P(0 Z 2.17) = (2.17) - (0) We have to check standard normal table for the values 2.17 and 0 Therefore, P(0 Z 2.17) = 0.9850 - 0.5000 = 0.4850 Hence, P(0 Z 2.17) = 0.4850.
