Question

Data from a study of ants in a country are presented in the accompanying table. The researchers recorded data on annual rainfal, maximum daily temperaure, and number of ant species at each of 11 study sites. Complete parts a through c below Cick here to view the simple Inear regression outest for anrual rairfal and temperature a Consider a straight-line model rolating annual rainall y) and masimum daily lerperatlure (x), The acompanying table shos technology oubut of the simple linear regression Give the least squares predicion equation (Round to two decimal places as needed.) b. Construct a scatterplot for the analysis in part a Include the least squares line on the plot. Does the line appear to be a good predictor of annual raindal? 0 8 2a Does the line appear to be a good predictor of amual rainlall? O A Yes, since the line passes near the data points O B. No, since the line does not pass through any of the dala points O C. No. since the line is not close to the data points 0 D. Yes, since the ine passes through all of the data points ?.New consder a straightine model relating number of ant species (yjbrrual rantal (x)Onthe bass of he accompanying lechology oubd. eepeal pard a and b
