an article in the Journal of Environmental Engineering (Vol. 115, No. 3, 1989, pp. 608-619) reported the results of a study on the occurrence of sodium and chloride in surface streams in central Rhode Island. The following data wre chloride soncentration y (in milligrams per liter) and roadway area in the watershed x (in percentage). Does a simple linear regression model seem appropriate here? Fit the simple linear regression model using the method of least squares.What is the least squares model of the slope? What is the least square model of the y-intercept? Round off your answer to three decimal points.

A recent 6-week study randomly assigned lab mice to one of three conditions: LD (Group 1) had a standard light/dark cycle cach 24-hour period; (Group 2) LL had bright light all the time, and (Group 3) DM had dim light when there nomally would have been darkness. The rescarchers hoped to investigate...
