Homework Answers
(A) right choice is C.42%
following frequency distribution has been generated using ms-excel. since the % cf of the class 4-8 is 42.42 , so right choice should be 42%
| Class interval | frequency(f) | cumulative frequency (cf) | % f | %cf |
| 0--4 | 4 | 4 | 12.12 | 12.12 |
| 4--8 | 10 | 14 | 30.30 | 42.42 |
| 8--12 | 6 | 20 | 18.18 | 60.61 |
| 12--16 | 6 | 26 | 18.18 | 78.79 |
| 16--20 | 5 | 31 | 15.15 | 93.94 |
| 20--24 | 2 | 33 | 6.06 | 100.00 |
(B) right choice is : skewed to the right
since the histogram has tailed towards right, so shape of graph is skewed to right
