Use the raw data in this tab to estimate the mean change in the concentration of LDL cholesterol for 1) a person who followed the low cholesterol diet and 2) a person who followed the low saturated fat diet. Additionally, estimate the standard deviation of the linear relationship between the type of diet and the change in the concentration of LDL cholesterol. Create a single plot of a linear relationship between the type of diet (categorical variables: low cholesterol vs. low saturated fat) and the change in the concentration of LDL cholesterol (mg/dL). Refer to Acts 1 and 2 for formatting and rounding instructions. You will be graded on your ability to format figures and utilize formulas to calculate the standard deviation and means.
