The distance (in km) of 40 engineers from their residence to their place of work were found as follows: 5 3 10 20 25 11 13 7 12 31 19 10 12 17 18 11 32 17 16 2 7 9 7 8 3 5 12 15 18 3 12 14 2 9 6 15 15 7 6 12 Construct a grouped frequency distribution table with class size 5 for the data given above taking the first interval as 0-5 (5 not included). What main features do you observe from this tabular representation?

In a class of 60 students, the average age of 25 girls is 12 yr and boys is 14 yr. Two of the students aged 16 and 14 yr leave the class and are replaced by 3 students of ages 12,11 and 10 yr, Find the change in average age of the class.

Form a grouped frequency distribution from the following data by inclusive method taking 4 as the class size of class intervals. 31, 23, 19, 29, 22, 20, 16, 10, 13, 34, 38, 33, 28, 21, 15, 18, 36, 24, 18, 15, 12, 30, 27, 23, 20, 17, 14, 32, 26, 25, 18, 29, 24, 19, 16, 11, 22, 15, 17,10
