Question: Manufacturers of womens’ fashion accessories were interested in how a woman’s WAIST size (in inches) relates to various explanatory variables. One such variable considered was the woman’s AGE (in years). They had data on 20 randomly selected Canadian women; part of that data is shown here:

1. (2 points) The value of R-Sq is not on the printout. Calculate R-Sq (but don't interpret the value).
2. (3 points) Use the equation of the least squares regression line to find the predicted waist size, and the residual, for woman #2.
3. (6 points) Calculate a 95% confidence interval for the slope, and interpret the interval in context.
4. (2 points) State the 95% confidence interval on the output for the mean waist size of 22—year-old women. Interpret the interval in context.
