**Question **4. Construct a frequency distribution table for the number given below, using the class intervals 21-30, 31-40 … etc. 75, 67, 57, 50, 26, 33, 44, 58, 67, 75, 78, 43, 41, 31, 21, 32, 40, 62, 54, 69, 48, 47, 51, 38, 39, 43, 61, 63, 68, 53, 56, 49, 59, 37, 40, 68, 23, 28, 36, 47

Use the table obtained to draw:

(i) a histogram

(ii) an ogive**Solution:**

**Question **5. (a) Use information given in the adjoining histogram to construct a frequency table.

**(b) Use this table to construct an ogive.Solution:**

**Question **6.

**(a) From the distribution, given above, construct a frequency table.(b) Use the table obtained in part (a) to draw; (i) a histogram (ii) an ogive.**

**Solution:**

(a)

The difference in consecutive class = 17.5 – 12.5 = 5

**Question **7. Use graph paper for this question. The table given below shows the monthly wages of some factory workers.**(i) Using the table, calculate the cumulative frequencies of workers.****(ii) Draw a cumulative frequency curve.****Use 2cm = Rs. 500 starting the origin at Rs. 6500 on x-axis and 2cm = 10 workers on the y-axis.**

**Solution:**

**Question **8. The following table shows the distribution of the height of a group of factory workers:

**(i) Determine the cumulative frequencies.(ii) Draw the ‘less than’ cumulative frequency curve on graph paper. Use 2cm = 5cm height on one axis and 2cm = 10 workers on the other.**

**Solution:**
