ANSWER:

The frequency distribution table for the given marks can be drawn as:

(i) The class interval (40−49) has the highest frequency and the class interval (90−99) has the lowest frequency.

(ii) In the class interval (30−39), the lower limit is 30 − 0.5 = 29.5 and the upper limit is

39 + 0.5 = 39.5.

(iii) The range of the given distribution is 97− 32 = 65.
