# What is the predicted cholesterol level

Q2 Regression- What is the predicted cholesterol level?

Given the data presented in Discussion Question 1 for this week, determine the cholesterol level of someone who drank two and a half cups of coffee a day. To get the answer, plot a regression line in StatCrunch and post your answers from StatCrunch for the following:

a) What is the intercept? (or –what would be your cholesterol level while ingesting no caffeine?)

The intercept is 665.71429

b) What is the slope? (or, what is what we call b in the linear regression equation?)

The slope is -0.69892857

c) What is the cholesterol level of someone who drank two and a half cups of coffee a day (given that 1 cup of coffee equals 100 mg of caffeine)?

The cholesterol level of someone who drank two and a half cups of coffee a day would be 490.98 mg/dL.

Simple linear regression results:

Dependent Variable: Cholesterol level (mg/dL)

Independent Variable: caffeine (mg)

Cholesterol level (mg/dL) = 665.71429 - 0.69892857 caffeine (mg)

Sample size: 7

R (correlation coefficient) = -0.72796194

R-sq = 0.52992859

Estimate of error standard deviation: 155.77582
