For a sample of 31 New England cities, a sociologist studies the crime rate in each city (crimes per 100,000 residents) as a function of its poverty rate (in %) and its median income (in $1,000s). He finds that SSE = 4,155,943 and SST = 7,675,381. a. Calculate the standard error of the estimate. (Round your answer to 4 decimal places.) b-1. What proportion of the sample variation in crime rate is explained by the variability in the explanatory variables? (Round your answer to 4 decimal places.)
