The distribution of heights of both five‑year old boys and seven‑year old boys is approximately Normal. The mean height of a fiv
Dafna11 [192]

Answer:

Kindly check explanation

Step-by-step explanation:

Given that :

5 years old:

Mean height (m) = 43

Standard deviation (σ) = 1.8

Height on fifth birthday (x) = 44

7 years old:

Mean height (m) = 48

Standard deviation (σ) = 2.1

Height on 7th birthday (x) = 49

To get the standardized score :

USe :

Zscore = (x - mean) / standard deviation

At 5 years:

Zscore = (44 - 43) / 1.8

Zscore = 1/ 1.8

Zscore = 0.556

At 7 years:

Zscore = (49 - 48) / 2.1

Zscore = 1/ 2.1

Zscore = 0.476

At the different ages, John's growth rate in height declined after the 5 th years as the standardized score at 5 years is greater than at 7 years.
