2 (a) The table shows the number of exercise classes attended in one week by each of 80 members of a gym. | Number of classes | 0 | 1 | 2 | 3 | 4 | 5 | | :---------------- | :-- | :-- | :-- | :-- | :-- | :- | | Frequency | 10 | 29 | 26 | 10 | 3 | 2 | (i) Find the mode. (ii) Find the median. (iii) A pie chart is drawn to show this information. Calculate the angle representing 5 classes attended. (b) Some members of the gym were surveyed about how much time they spent at the gym. The histogram shows the times, t minutes, they spent on their last visit. [Figure histogram of time (minutes) vs frequency density] (i) Thirty members spent between 30 and 60 minutes at the gym. Calculate the number of members surveyed. (ii) Rohit says: One tenth of these members spent longer than 1 1/2 hours at the gym on their last visit. Is he correct? Justify your answer.
