Actual commuting time in minutes (T) depends on both the weather, and the length of commute. Suppose on a given day T= (1 – Y)(15+ 15X) + Y(45 + 35X). The following table shows commuting times as a...


hi, this is econometry & statistic question. It asks







  1. Verify the value reported for T in the cell for (X = 0, Y = 1)




  2. Calculate E(T) and interpret the number you found.
