I’m having trouble with this regression problem we’re supposed to know for the final exam - particularly, finding the formula for the regression line. Any help would be appreciated!

The figure below shows a scatter plot of weight (in pounds) vs height (in inches) for a random sample 40 American men and the table shows linear regression table for that same data. We are curious if there is a relationship between height and weight.

a) Write down the hypothesis statement that we would check with this linear model.

b) Write out the formula for linear model.

c) What does the model predict for the weight of a man who is 70 inches tall?

d) State the conclusion of the hypothesis test from part ( c ).
