The percent data between 6.0 and 6.9 would be 13.59%. Here’s the complete solution for this specific problem.
z = (X - Mean)/SD
z1 = (6 - 5.1)/09 = + 1
z2 = (6.9 - 5.1)/09 = + 2
Required Percent = P(6 < X < 6.9)*100
= P(1 < z < 2)*100
= [P(z < 2) - P(z < 1)]*100
= [0.9772 - 0.8413]*100
= 0.1359*100
= 13.59%
I am hoping that this has answered your query.
