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.
