The following frequency distribution table shows the distances travelled by some rickshaws in a day. Observe the table and answer the following questions:
| Class (Daily distance travelled in km) | Continuous Classes | Frequency (Number of rickshaws) | Cumulative Frequency less than type |
| 60 -64 | 59.5 -64.5 | 10 | 10 |
| 65 -69 | 64.5 -69.5 | 34 | 10 +34 = 44 |
| 70 -74 | 69.5 -74.5 | 58 | 44 +58 =102 |
| 75 -79 | 74.5 -79.5 | 82 | 102 +82 =184 |
| 80 -84 | 79.5 -84.5 | 10 | 184 +10 =194 |
| 85- 89 | 84.5 -89.5 | 6 | 194 +6 =200 |
(i) Which is the modal class ? Why ?
(ii) Which is the median class and why ?
(iii) Write the cumulative frequency (C.F.) of the class preceding the median class.
(iv) What is the class interval (h) to calculate median?
