Answer: 59.02 inches.
Step-by-step explanation:
Given : The equation used to predict how tall a dog will be as an adult is [tex]\hat{y}=4.5 + 0.7x_1 + 0.55x_2[/tex] , where [tex]x_1[/tex] is the height of the mother and [tex]x_2[/tex] is the height of the father.
To predict the height of a puppy whose mother is 45.2 inches tall and whose father is 41.6 inches tall, we put [tex]x_1=45.2[/tex] and [tex]x_2=41.6[/tex] in the above equation, we get
[tex]\hat{y}=4.5 + 0.7(45.2) + 0.55(41.6)\\\\\Rightarrow\ \hat{y}=59.02[/tex]
Hence, the predicted height of a puppy = 59.02 inches.
