hello,
b) 62.47% of the students are between 14 and 18 years old.
step-by-step explanation:
mean = 15 and standard deviation = 2
student between 14 to 18
formula used z-score
for age 14 , z score
using z-table , p(z> -0.5)=0.3085
for age 18 , z score
using z-table , p(z< 1.5)=0.9332
p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247
thus, 62.47% of the students are between 14 and 18 years old.
