Answer:
The percentage is 95.45%
Step-by-step explanation:
In this question, we are tasked with calculating the percentage of oranges weighing between a particular range.
To do this , we use the z-scores of both numbers in the range.
Mathematically, z-score can be calculated as (x - Mean)/SD
Thus we have P(3 <x < 7) = P( (3-5)/1 < z < (7-5)/1)
= P( -2 < z < 2)
Using standard score table, we have
P(-2<z<2) = 0.9545
The percentage is thus 9545/100 = 95.45
