Regression Analysis?

Question

Regression analysis of free throws by 29 NBA teams during the 2002–2003 season revealed the

fitted regression Y = 55.2 + .73X (R2 = .874, syx = 53.2) where Y = total free throws made and

X = total free throws attempted. The observed range of X was from 1,620 (New York Knicks) to

2,382 (Golden State Warriors). (a) Find the expected number of free throws made for a team that

shoots 2,000 free throws. (b) Do you think that the intercept is meaningful? Hint: Make a scatter

plot and let Excel fit the line. (c) Use the quick rule to make a 95 percent prediction interval for Y

when X = 2,000

Any Help is appreciated....best answer?
