Draw a
Answer to Problem 23AYU
Explanation of Solution
Given information:
A biologist would like to know how age of mother affects the incidence rate of Down syndrome the data to the right represent the age of the mother and the incidence rate of Down syndrome per
Draw a scatter diagram treating age of the mother as the independent variable would it make sense to find the of best fit for these data? Why or why not?
Calculation:
Consider the table,
The scatter diagram is,
There is line to fit the data a linear pattern. It is for sure a curve that is increasing with the values of
As the age of mother increases the chances of Down syndrome drastically increases.
Hence,the Down syndrome drastically increases with age of the mother increases.
