Homework Answers
We know that z =( x-mean)/ SD
From the given data mean = 4.8
SD = 0.4
So , 5.2 < x can be changed to
= (5.2 - 4.8)/0.4 < (X-mean)/SD
= 1 < z
Option d

Normal Distribution Problem. Red Blood Cell Counts are expressed millions per cubic millimeter of whole blood. For healthy females, x has a approximately normal distribution with mu = 4.8 and sigma =.3. Note: my probabilities are exact probabilities. Solutions using the standard normal table will be close. What is the probability that a healthy female has a red blood count between 3.9 and 5.0? .4787 .2475 .7248 .7462
