A linear regression plot, showing height as a function of age

1 About how many inches are kids in this dataset expected to grow per year?

2 At that rate, if a child were 45" tall at age eight, how tall would you expect them to be at age twelve?

3 At that rate, if a ten-year-old were 55" tall, how tall would you expect them to have been at age 9?

4 Using the equation, how tall would you expect a seven-year-old child to be?

5 How many of the seven-year-olds in this sample are actually that height?

6 Using the equation, determine the expected height of someone who is…​

7.5 years old 13 years old 6 years old newborn 90 years old

7 For which ages is this predictor function likely to be the most accurate? Why?

8 For which ages is this predictor function likely to be the least accurate? Why?
