Cholesterol can be a real problem for people because of our fast-paced lives. The mean level for the population is 255 with a standard deviation of 25. A group of patients took a new statin drug that was thought to change the levels as compared to the population. At a = 0.01, do the data %3D support the claim that the statin drug worked? State the null and alternative hypotheses, provide the mean and standard deviation of the sample, the standardized test statistic, the critical value, your decision, the potential error and your general conclusion. If you choose to use SPSS, please email your output. If you choose to do it by hand, please show your work.

Expert Solution
Step 1

Null and alternate hypotheses:

The investigator is interested to test whether there is a change in the cholesterol level after taking statin drug.

Denote the population mean cholesterol of patients after taking statin drug as μ.

It is given that the mean level of cholesterol for the population is 255 with a standard deviation of 25.

The hypotheses are given below:

Null hypothesis:

H0 : μ = 255

That is, the population mean level of cholesterol after taking statin drug is equal to 255.

Alternative hypothesis:

Ha : μ ≠ 255 (Two tail test).

That is, the population mean level of cholesterol after taking statin drug is significantly different from 255.
