A researcher wanted to know what determines the percentage of female representation in state legislatures (PCTWMLEG). She ran a regression model with one independent variable: LABORFEM (female labor force participation, in percent). Thus, the regression model can be written asPCTWMLEG=?+?LABORFEM+.

The results of this regression are shown below:

. reg potwmleg laborfem Num of obs = 50 F( 48) = 19.48 Prob > F 0.0000 R-squared = 0.4532 Adj R-squared = 0.4299 Rool MSL 6.1879 petwmleg | Coel. Std. Err. t PIt 195% CI] ------F----- laborfem | .5221128 .2104935 2.48 0.017 0986545 9455711 cons -7.904346 12.86599 -0.61 0.542 -33.78738 17.97869
