6)P(40 less than or equal to x less than or equal to 47); u = 50; o = 15
10) P( x greater than or equal to 2); u = 3; o = 0.25
Find the z value described and sketch the area described.
14) find z such that 97.5% of the standard normal curve lies to the left of z.
18) find z such that 95% of the standard normal curve lies to the right of z.© BrainMass Inc. brainmass.com October 9, 2019, 10:00 pm ad1c9bdddf
