Chapter , Problem 102SE

(choose chapter or problem)

An article in Air and Waste [“Update on Ozone Trends in California’s South Coast Air Basin” (1993, Vol. 43)] reported on a study of the ozone levels in the South Coast air basin of California for the years 1976–1991. The author believes that the number of days that the ozone level exceeds 0.20 parts per million depends on the seasonal meteorological index (the seasonal average 850 millibar temperature). The data are in Table E11-18:

(a) Construct a scatter diagram of the data.

(b) Fit a simple linear regression model to the data. Test for significance of regression.

(c) Find a \(95 \%\) CI on the slope \(\beta_{1}\).

(d) Analyze the residuals and comment on model adequacy.
