Calculating standard error and least square regression. Data table in gif format.

Refer to the attachment below for accurate data.

A doctor wanted to determine whether there is a relation between a
male's age and his HDL (so called good) cholesterol.  He randomly selected 17 of his patients and determined their cholesterol.  

a. Determine the least-squares regression equation from the sample
data.

b. Compute the standard error of y'

c. Compute the standard error of the slope "b" (note y' = a + bx)

d.Construct a 95% confidence interval about the slope.

e. Suppose a 42 year old man vists the doctor's office.  What would be a good guess as to the HDL cholesterol of this patient?
