A study was done in a large undergraduate classroom asking the students to record how many hours they spent doing homework on a typical day rounded to the nearest hour. The data was organized by recording the number of hours (X) and the number of students who responded with that number of hours (frequency). X(# of hours) Frequency of X=x x = 0 7 x = 1 7 x = 2 13 x = 3 4 x = 4 2 Based on these findings, what is the expected number of hours than a student selected at random from this classroom would spend studying each day?
