Tell whether correlation is being used correctly. Identify any statistical errors.The correlation coefficient for the data shown in the scatter plot is close to -1 so the slope of the regression equation that goes through the points will be close to -1. 
What will be an ideal response?
Incorrect. The slope of the regression equation is not the same as the correlation coefficient. The correlation coefficient indicates how close the points will lie to a straight line but not what the slope of that line will be.

Use the guidelines to evaluate the study. Discuss flaws that you see in the study. A pharmaceutical company wants to test its new medication to lower blood pressure. It randomly selects 1000 people with high blood pressure and randomly assigns each person to one of two groups. The first group receives the medication for a month and also suggestions as to how to improve their diet. The control group receives a placebo medication and no dietary suggestions. At the end of the month each person's blood pressure is again taken. The average change in blood pressure is compared for the two groups.
