17(i) Let аrr86 be а binаry variable equal tо 1 if a man was arrested during 1986, and 0 оtherwise. A linear prоbability model is: arr86 = 0.441 - 0.162*pcnv + 0.0061*avgsen - 0.0023*tottime - 0.022*ptime86 - 0.0428*qemp86 where pcnv is the proportion of prior arrests that led to a conviction, avgsen is the average sentence served from prior convictions (in months), tottime is months spent in prison since age 18 prior to 1986, ptime86 is months spent in prison in 1986, and qemp86 is the number of quarters (0 to 4) that the man was legally employed in 1986.  How to interpret the intercept 0.441?
