Just need both sides of question K answered the mean and bel

the mean and below z is about 16% of the area under the normal curve. variable with a mean of 28 and a standard deviation of 7, find the following probabilities: P(x

Solution

P(Area between mean and z) = 0.34

Z = 0.995 (from the table)

---------------------------------

Area = 0.92 to the left of z means

P(x<z) = 0.92

Z value = 1.405
