80% is the score percentage
Answer:
The z-score is -2
Step-by-step explanation:
Here, we are asked to calculate the z-score of the height.
Mathematically, we can calculate z-score by using the formula below;
z-score = (x-mean)/SD
According to this question, mean = 44cm and SD = 3cm with x here = 38cm
Plugging these values into the z-score equation, we have
z-score = (38-44)/3 = -6/3 = -2
Firstly add 7 to both sides= x/3= 5
Times by 3 on both sides to get x on its own= x= 15
Its either x=2 or no solution let me work out the problem.
