Question

Construct a frequency distribution table for the following weights (in grams) of 35 mangoes, using the equal class intervals, one of them is 40 – 45 (45 not included). 

30, 40, 45, 32, 43, 50, 55, 62, 70, 70, 61, 62, 53, 52, 50, 42, 35, 37, 53, 55, 65, 70, 73, 74, 45, 46, 58, 59, 60, 62, 74, 34, 35, 70, 68. 

(a) How many classes are there in the frequency distribution table? 

(b) Which weight group has the highest frequency?

Answer 1

First, we have to arrange weights (in grams) of 35 mangoes in an ascending order.

= 30, 32, 34, 35, 35, 37, 40, 42, 43, 45, 45, 46, 50, 50, 52, 53, 53, 55, 55, 58, 59, 60, 61, 62, 62, 62, 65, 68, 70, 70, 70, 70, 73, 74, 74.

Now, we will draw the frequency table of the given data.

(a) There are nine classes in the frequency distribution table.

(b) 70 – 75 weight has the highest frequency.
