Question 1

A breeder of Thoroughbred horses wishes to model the relationship between the gestation period and the length of life of a horse. The breeder believes that the two variables may follow a linear trend. The information in the table was supplied to the breeder from various thoroughbred stables across the state.

Summary statistics yield SS_xx = 21,752, SS_xy = 236.5, SS_yy = 22,

= 332, and

= 22.5. Find a 95% prediction interval for the length of life of a horse that had a gestation period of 300 days. Use

as an estimate of σ and use

Question 2

Consider the following pairs of observations:

x	2	0	3	3	5
y	1	3	4	6	7

a.	Construct a scattergram for the data.

b.	Find the least squares line, and plot it on your scattergram.

c.	Find a 99% confidence interval for the mean value of y when x = 1.
