Question

The following distribution represents the number of hours spent per year by a group of sports person in going to the gym. Find the median number of hours spent per by the sports persons in going to the gym.

• A. $335.5$
• B. $333$
• C. $350$
• D. $320$

Answer 1

The correct option is A $335.5$

Let us convert the class intervals given, to class boundaries and construct the less than type cumulative frequency distribution.

Here,
Here, the cumulative frequency just greater than or equal to 150 is 198.
And the less than type cumulative frequency corresponding to the class boundary is 399.5
299.5-399.5 is the median class

So, the median number of hours spent per year by this group of 300 sports person in going to the gym is 335.5.
