Question

Attempt the following:
The table gives the ages of husbands and wives:
Find: a. The marginal frequency distribution of the age of husbands.
b. The conditional frequency distribution of the age of husbands when the age of wives lies between 25-35.

Answer 1

Marginal frequency distribution of husband's age=Sum of individual columns of table

Age $20-30$ $30-40$ $40-50$ $50-60$ Total

Number $5$ $20$ $44$ $24$ $93$

Marginal frequency distribution of husband's age wives age$=25-35$

Age $20-30$ $30-40$ $40-50$ $50-60$ Total

Number $-$ $10$ $25$ $2$ $37$

(Values of men's age in the columns corresponding to wives age $25-35$ row)
