My research question is: Do number of children and time since consuming last coffee of the day each predict amount of sleep someone has? The best information from a regression model to address this research question would be: O a. The F-statistic, p-value, and R-square O b. The constant term O c. The beta, t-statistic, and p-values of either "number of children' or 'time of coffee consumption' O d. The betas, t-statistics, and p-values of 'number of children' and 'time of coffee consumption
