The use of two-sample t procedures assumes that the sample means follow a Normal distribution. However, in this case, the distribution of pulse rate in each group is not Normal.
How to explain the informationWe can use a two-sample t-test to compare the mean pulse rates for the beta blocker and placebo groups. The point estimate of the difference in means is: 65.2 - 70.3 = -5.1
The standard error of the difference in means is: = 2.553
Therefore, the 99% confidence interval for the difference in mean pulse rates is: (-11.0, 0.8)
We are 99% confident that the true difference in mean pulse rates between the beta blocker and placebo groups is between -11.0 and 0.8 beats per minute.
c. The 99% confidence level means that if we were to repeat this study many times, we would expect 99% of the resulting confidence intervals to contain the true difference in mean pulse rates.
