Problem 10CQQ

In Exercises, assume that red blood cell counts of women are normally distributed with a mean of 4.577 and a standard deviation of 0.382.

What percentage of women have red blood cell counts in the normal range from 4.2 to 5.4?

Step-by-Step Solution:
Step 1 of 3

Problem 10CQQ

Step1 of 3:

We have red blood cell counts of women are normally distributed with a mean of 4.577 and a standard deviation of 0.382.

Step2 of 3:

We need to find what percentage of women have red blood cell counts in the normal range from 4.2 to 5.4?

Step3 of 3:

We have 1).Consider z statistics with P( ) = P(z  )

= P(z  )

= P(z -0.99)

= 0.9842

Probability that -0.990 is calculated by using standard normal table(area under normal curve).in statistical table we have to see row -0.9 under column 0.00

Hence, P(z -0.99) = 0.9842

2).1).Consider z statistics with P( ) = P(z  )

= P(z  )

= P(z 2.15)

= 0.1611

Probability that 2.15 is calculated by using standard normal table(area under normal curve).in statistical table we have to see row 2.1 under column 0.05

Hence, P(z 2.15) = 0.1611

Now,

The percentage of women have red blood cell counts in the normal range from 4.2 to 5.4 is given by

P( ) - P( ) = 0.9842 - 0.1611

= 0.8231

Conclusion:

Therefore,82.31% of women have red blood cell counts in the normal range from 4.2 to 5.4.
