A research center is interested in investigating about height and age of children who are between 5 to 9 years old. In order to do this, a sample of 15 children is selected and the data is given below. The scatter chart for this data is presented below with age as the independent variable and Height as the dependent variable. y = 27.9140 +2.7395x The estimated regression equation used estimate the height based on the age is 60 50 40 Height (inches) 30 20 10 0 0 8 10 4 6 Age (in years) a. Given what does the scatter chart indicate about the relationship between the height and age of children? [3pts] b. Interpret the y-intercept b0 in a sentence. [3pts] c.
