Is there a difference in the average time spent reading for fun between males and females? A random sample of 213 adults was taken. The following $\mathrm{R}$ output was from a regression analysis with time spent reading (in minutes per day) as the response variable and gender as the explanatory variable (coded O for males and 1 for females). Coefficients: $\begin{array}{lrlrr} & \text { Estimate Std. } & \text { Error } & \text { value } & \text { Pr }(>\mathrm{t}| \text { (Intercept) } & 29.910 & 3.591 & 8.328 & 1.03 \mathrm{e}-14 \\ \text { gender } & 1.542 & 4.707 & 0.327 & 0.744\end{array}$ Which of the following is the best interpretation of the $y$- intercept of the least-squares regression equation in the context of the problem? The predicted reading time for $x=0$ is $29.910$ minutes per day. The predicted reading time for females is $29.910$ minutes per day. The predicted reading time for males is $29.910$ minutes per day. The reading time for males is predicted to be $29.910$ minutes more per day than for females. The reading time for females is predicted to be $29.910$ minutes more per day than for males. SP.AS357
