Question 13 0.31 pts A researcher wants to study the relationship between women's ages and number of births per year for women in the 10 to 55 age range. The relationship would be expected to be a linear relationship O nonexistent nonlinear a negative correlation

Answer 1

The relationship expected to be a nonlinear relationship. A nonlinear relationdhip explains that the each unit change of one variable will not always make the same change in other variable. Here age ranging from 10 to55 doesn't make a propotional relation to the birth rate.

A linear relation means both variable are related in a linear way. If one variable increases the other also will increase. So this is not the correct choice.

Nonexistent relationship means there is no corelation, if a change in X has no impact on Y. However here, before puberty there no child birth and after puberty there is child birth. After middle age there is less probability for child birth and after menopause there is no childbirth. So women's age and birth rate are some how related. Therefore this is a wrong choice.

A negative corelation means inverse relationship between two variables. So this choice is not the correct choice.
