The number of students that spend more than 10 hours watching television = 39

Therefore, given that less than half of the student spend more than 10 hours watching television, the statement is false

Part B

The number of students that watch 3 hours of television is the highest than any other time range with 16 students, therefore, the statement is true

Part C
