3. Ryan is raising fruit flies as a science project. The table shows the frequencies of the lifetimes of the flies. Lifetime (days) 5-7 Frequency 1 7-9 3 9-11 13 11-13 24 13-15 27 15-17 20 17-19 9 19-21 3 a) Sketch a frequency histogram for these data. b) Sketch a frequency polygon for these data. c) Estimate the mean life of the fruit flies. 3.
