a. Eyeball the data. Does the correlation between x and y look positive, negative or close to 0? What does it mean if it is
significantly close or away from 0?
b. Find the mean and standard deviations of x & y as well as the correlation (you can use a calculator or computer).
c. Build a linear regression line.
d. Plot a histogram of the residuals. What value do you get for the standard error of the residuals? How does that
number relate to your histogram?
e. Build a 95% confidence interval for your slope.
