# Normal Serum Hemocrit

The normal serum hemocrit level is 0.41 milligrams to 100 milligrams of blood. The level in elderly patients is significantly low at 0.31.

25 patients out of 100 are normal levels. The standard deviation is 0.6. A medication that is designed to increase the hemocrit

is taken in 100 patients for one month. A testing is found that 45 patients have a mean average of 0.38 milligrams. As 0.1% does the medication increase the hemocrit levels?

A. States the null and alternative hypothesis

B. Define the statistic test

C. Develop the decision rul.

D. Compute the test statistic.

E. State the conclusion.

#### Solution Preview

We should first calculate the average NORMAL SERUM HEMOCRIT LEVEL of people before medication and after medication.

<br>The weighted mean of population before medication is M1= 0.41*25/100+0.31*(1-25/100)=0.335

<br>Our after medication sample mean is M2 = ...
