2. The data below represent the results of a study of days actually spent in jail for fifteen people convicted of riot-related crimes in summer 2020. The researchers hope to determine useful variables for predicting time spent in jail for those convicted of similar crimes in 2021. The variables investigated are: X₁-measure of judge's caseload, X2-number of legal motions filed, X3-age of defendant, X4- seriousness of offense, and Y-days actually spent in jail. Perform the complete appropriate analysis (i.e., choose the best model for predicting days actually spent in jail and check all assumptions) - be sure to fit the best model using a 10% significance level for any hypothesis tests.

The data below represent the results of a study of days actually spent in jail for fifteen people convicted
of riot-related crimes in summer 2020. The researchers hope to determine useful variables for
predicting time spent in jail for those convicted of similar crimes in 2021. The variables investigated
are: X₁-measure of judge's caseload, X2-number of legal motions filed, X3-age of defendant, X4-
seriousness of offense, and Y-days actually spent in jail. Perform the complete appropriate analysis
(i.e., choose the best model for predicting days actually spent in jail and check all assumptions) - be
sure to fit the best model using a 10% significance level for any hypothesis tests.
