Answer:
An applicant must score a minimum of 128
Step-by-step explanation:
To solve this question, we make use of the z-score formula.
Z = (X - mean)/standard deviation
Firstly, let’s list out the parameters from the question. From the question, we can deduce that:
Z = 1.5
X = ?
Mean = 110
Standard deviation =12
1.5= (X-110)/12
18 = X - 110
X = 110 + 18
X = 128
Tom=36
Maya=32
Tom= 2/3=perfect attendance 24/2= 12 12= 1/3 12x3(3/3)= 36
Maya=3/4 perfect attendance 24/3= 8 8=1/4 8x4(4/4) =32
Hope it helps :)
