Question: Refer to the Journal of Biogeography Dec 2003 study of

Refer to the Journal of Biogeography (Dec. 2003) study of ants in Mongolia, presented in Exercise. Data on annual rainfall, maximum daily temperature, and number of ant species recorded at each of 11 study sites are listed in the table and saved in the GOBIANTS file.
a. Consider a straight-line model relating annual rain fall (y) and maximum daily temperature (x). A MINITAB printout of the simple linear regression is shown below. Give the least squares prediction equation.
b. Construct a scatterplot for the analysis you performed in part a. Include the least square line on the plot. Does the line appear to be a good predictor of annual rainfall?
c. Now consider a straight-line model relating number of ant species (y) to annual rainfall (x). On the basis of the MINITAB printout below. repeat parts a and b .
