Question
10. Construct a frequency distribution table for the following weights (in gm) of
30 oranges using the equal class intervals, one of them is 40-45 (45 not included).
The weights are: 31, 41, 46, 33, 44, 51, 56, 63, 71, 71, 62, 63, 54, 53, 51, 43,
36, 38, 54, 56, 66, 71, 74, 75, 46, 47, 59, 60, 61, 63.
(a) What is the class mark of the class intervals 50-55?
(b) What is the range of the above weights?
(c) How many class intervals are there?
(d) Which class interval has the lowest frequency?
