Based on previous scores, after studying for 5.5 hours, everyone received above a 60. If Becky studied for only 3 hours, she would have a very low chance of receiving above a 60, as this is the first study-time that someone received a 60. At more than 10 hours, she would obviously have a better chance, but it is not the minimum amount of time that Becky could use.
