Problem 1:

A. Verify the regression model assumptions.

B. Perform the hypotheses test for the linear relationship between x and y, using level of significance =0.05.

The accompanying table shows the teams winning percentage (x) and power rating (y) for the 2011 NCAA basketball tournament.

School	Win % (x)	Rating (y)
OSU	91.9	121
Kansas	92.1	119.5
SD state	91.4	118.1
Duke	86.5	117.8
Connecticut	77.5	117.5
Pitt	82.4	116.9
Kentucky	76.3	116.6
ND	79.4	116.3

Problem 2:

Listed in the table are the low (x) and high (y) temperatures for a particular day in 2006, measure in degrees Fahrenheit, for a random sample of cities worldwide.

City	Low(x)	High(y)
Kolkata	57	77
London	36	45
Montreal	7	21
Rome	39	55
San juan	70	83
shanghai	34	45

Refer to above data.

a. Construct a 99% prediction interval for the high temp for a randomly chosen city with a low temp of 30 degrees.

b. Which of the intervals you constructed is wider and why?
