Then,

Question 6

In a study of diabetic patients in a village, the following observation were noted .

Age in year	10-20	20-30	30-40	40-50	50-60	60-70
No. of patients	2	5	12	19	9	4

Represent the above data by a frequency polygon.

Answer 6

Represent the above data by a frequency polygon –

We plot the following points on the graph : (5, 0), (15, 2), (25, 5), (35, 12), (45, 19), (55, 9), (65, 4) and (75, 0) and join them to form a frequency polygon as given below :

Question 7
