Question

Heart disease patients often experience spasms of the coronary arteries. Because biological amines may play a role in these spasms, a research team measured amine levels in coronary arteries that were obtained postmortem from patients who had died of heart disease and also from a control group of patients who had died from other causes. The following table summarizes the concentration of the amine serotonin ( NG/GM). Use a t-test to compare the means at the 5% significance level.

Answer 1

A t-test can be used to compare the means of amine levels in coronary arteries of heart disease patients and a control group.

Step-by-step explanation:

To compare the means of amine levels in coronary arteries of heart disease patients and a control group, a t-test can be used. The t-test compares the means of two groups to determine if they are significantly different. At the 5% significance level, the t-test calculates the p-value, which represents the probability of obtaining the observed difference (or more extreme) by chance. If the p-value is less than 0.05, it indicates there is a significant difference between the means.
