Problem 30E

Find the following percentiles for the standard normal distribution. Interpolate where appropriate. a.? ?91st b.?? th c.? ?75th d.? ?25th e.?? th

Step-by-Step Solution:

Answer : Step 1 of 5 : The claim is to find the percentiles for the standard normal distribution. a) We have to find the z value for 91 st percentile P(Z z ) = 0.91 We have to check standard normal table for the value 0.91 91 lies in 1.3 row and 4th column Therefore, z = 1.34 Hence, P(Z 1.34 ) = 0.91
