# The marketing manager of a large supermarket chain would like to

The marketing manager of a large supermarket chain would like to determine the effect of shelf space (in feet) on the weekly sales of international food (in hundreds of dollars). A random sample of 12 equal –sized stores is selected, with the following results:

 Shelf Space (X) Weekly Sales(Y) 10 2 10 2.6 10 1.8 15 2.3 15 2.8 15 3 20 2.7 20 3.1 20 3.2 25 3 25 3.3 25 3.5

1. Find the equation of the regression line for these data. What is the value of the standard error of the estimate? Place your answer, rounded to 3 decimal places, in the blank. Do not use a dollar sign. For example, 0.345 would be a legitimate entry.
2. Find the equation of the regression line for these data. What is the value of the coefficient of determination? Place your answer, rounded to 3 decimal places, in the blank. Do not use a dollar sign. For example, 0.345 would be a legitimate entry.
