Answer:
81.8%
Step-by-step explanation:
Mean =
Standard deviation =
Now we are supposed to find out what percent of the numbers fall between 35 and 50
Substitute the values
Now for P(35<x<50)
Substitute x = 35
Substitute x = 50
So, P(-1<z<2)
P(z<2)-P(z<-1)
=0.9772-0.1587
=0.8185
=
=81.8%
Hence 81.8% percent of the numbers fall between 35 and 50
