Problem 4E

In a study similar to the one in Exercise 3, the relative humidity and ozone levels were measured for 120 days in another city. The MINITAB output follows. Assume that assumptions 1 through 4 on page 540 hold.

 The regression equation is Ozone = 29.7 - 0.135 Humidity Predictor Coef SE Coef T P Constant 29.703 2.066 14.38 0.000 Humidity -0.13468 0.03798 -3.55 0.001 S = 6.26 R-Sq = 9.6% R-Sq(adj) = 8.9%

a. What is the slope of the least-squares line?

b. Find a 95% confidence interval for the slope

c. Perform a test of the null hypothesis that the slope is greater than or equal to -0.1. What is the P-value?
