1.In the course of an experiment, 15 mosquitoes were put in each of 120 jars and were next subjected to a dose of D.D.T. After 4 hours the number alive in each jar was counted and the following frequency distribution was obtained:
No. of mosquitoes alive
0
1
2
3
4
5
6
7
8
Frequency (no. of jars)
2
12
14
22
28
17
13
10
2
Find the frequencies that one would expect on the assumption that each mosquito has a common probability of survival.
