Explanation / Answer

Solution 22:

a. Since it is a normal distribution, highest frequency would be in the centre. Therefore, the remaining three frequencies would be 14, 8 and 5.

b.  Since it is a normal distribution, highest frequency would be in the centre. Therefore, the remaining four frequencies would be 17, 17, 5 and 1.

Solution 23:
