Question

Find two lines of regressions from the following Data:

Age of husband : 25, 21, 22.5, 26.3, 35.7, 20.8, 22.9, 40.6, 25.2, 18.1

Age of wife: 16.3, 15.1, 20.9, 17.0, 22.6, 14.3, 18.9, 21.0, 15.6, 14.8

Estimate the following:

a. The age of husband when age of wife is 21.5

b. Age of wife when age of husband is 45.9

c. The correlation coefficient.

Definition Definition Relationship between two independent variables. A correlation tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
