1.       Determine the correlation between glucose, triglycerides, TC, LDL & HDL levels.

1. 1. Insert correlation table.

1. 1. Which correlation procedure (Pearson or Spearman) did you choose and why?
   2. Which correlation is the most positive? Is this a weak, moderate, or strong correlation?
   3. Which correlation is the most negative?
   4. Write an overall interpretation of the correlation findings that addresses the strength, direction, and significance of the correlations.

1. Run a linear regression for total cholesterol with LDL as a predictor.

1. 1. Is the model significant? How can you tell (provide objective data)?
   2. What is your dependent variable?
   3. What percent of TC is explained by LDL?
   4. Write a regression equation to predict TC based on LDL.
   5. Use your regression equation to predict my TC if my LDL is 145. (show equation and answer)
   6. What range of TC do you expect would give you 95% accuracy of prediction for someone with an LDL of 145?
   7. Insert regression tables to support answers

1. Run a linear regression for HDL with both triglycerides and gender as predictors

1. 1. Is the model significant?
   2. Which independent variable contributes most to the equation?
   3. What is the coefficient of determination value?
   4. What percent of HDL is explained by these 2 variables together?
   5. Insert regression table to support answers.
   6. Write a summary statement describing your findings.
