Question
A clinical researcher performs a clinical trial on 19 patients to determine whether a drug treatment has an effect on serum glucose. The sample mean glucose of the patients before and after the treatment are summarized in the following table. The sample standard deviation of the differences was 10.
| Sample mean glucose (mg/dL) | |
|---|---|
| Before treatment | 80 |
| After treatment | 72 |
What type of hypothesis test should be performed? What is the test statistic? What is the number of degrees of freedom? Does sufficient evidence exist to support the claim that the drug treatment has an effect on serum glucose at the α=0.05 significance level?
