There is an approximate linear relationship between the height of females and their age (from 5 to 18 years) described by the equation Height = 50.3+6.1(Age), where height is measured in centimeters and age in years. Which one of the following statements must be true? O a The estimated slope is 6.1, which implies that female children between the ages of 5 and 18 increase in height by about 6.1 cm for each year they grow older. O b My niece is 8 years old and is 115 cm tall. She is shorter than average for girls her age. Oc The heights of 68% of female children who are 10 years old are within 6.1 cm of 110.4 cm. Od The estimated intercept is 50.3 cm. We can conclude from this that the typical height of female children at birth is 50.3 cm. O e The correlation between Height and Age is negative.
