Listed below are the numbers of cricket chirps in 1 minute and the corresponding temperatures in
degreesF.
Find the regression equation, letting chirps in 1 minute be the independent (x) variable. Find the best predicted temperature at a time when a cricket chirps
3000
times in 1 minute, using the regression equation. What is wrong with this predicted temperature? Use a significance level of 0.05.
