d. between the ages of 8 and 12, all four boys had the biggest jump in height.

Answer 1

C. because all four boys had over a foot of jump in height between the age of 12 and 16 which is the greatest, on-average jump.

Answer 2

The correct option is: Option: c

c. between the ages of 12 and 16, all four boys had the biggest jump in height.

Explanation:

age 8 age 12 age 16 age 20 age 24

paul 4 ft 8 in 5 ft 0 in 5 ft 11 in 6 ft 1 in 6 ft 1 in

bruce 4 ft 6 in 4 ft 11 in 5 ft 10 in 6 ft 1 in 6 ft 1 in

tom 4 ft 9 in 5 ft 0 in 6 ft 0 in 6 ft 2 in 6 ft 2 in

steve 4 ft 7 in 4 ft 11 in 5 ft 11 in 6 ft 1 in 6 ft 1 in

• By looking at the table we could observe that the increase in their height is not steady that is they do not grow by a constant rate as between age 8 to age 12 there is a small variation in their height while during age 12 to age 16 there is a higher variation in their height i.e. they grow at a faster rate.

• Also growth spurt means that there is a sudden growth in one's body but that is not happening at the age of 20.

Hence, the correct answer is:

c. between the ages of 12 and 16, all four boys had the biggest jump in height.

( As there is a increase of about 1 ft in everyone's height in that age group)
