The following data shows the results from a medical study that looked at the number of years that a person has smoked and the percentage of lung damage they have sustained. The results are as follows:

# of Years (x)	22	14	31	36	9	41	19	8	28	18
% lung damage (y)	20	12	54	63	17	71	23	15	47	13

1. Determine the coefficient of correlation and interpret.
2. Determine the coefficient of determination and interpret.
3. Determine the regression equation.
4. Determine the standard error of the estimate.
5. Calculate the 90% confidence interval for the percentage of lung damage sustained for someone who has smoked for 25 years.
