Question: Cholesterol, finis. Based on the regression output seen in Exercise 8, create a 95% confidence interval for the slope of the regression line and interpret it in context.
Exercise: Cholesterol 2007. Does a person's cholesterol level tend to change with age? Data collected from 1406 adults aged 45 to 62 produced the regression analysis shown. Assuming that the data satisfy the conditions for inference, examine the association between age and cholesterol level.
Dependent variable is: Chol

a) State the appropriate hypothesis for the slope.
b) Test your hypothesis and state your conclusion in the proper context.
