Answer:
Graph is attached below
Explanation:
Normal curve with mean 50 and standard deviation of 2
Normal curve is like inverted U shape
Mean is the middle line on the curve
So we put 50 on the middle liine
We have one , two and three standard deviation
To get first standard deviation we add 2 with mean 50= 52
To get second standard deviation we add 2 with mean 52=54
To get third standard deviation we add 2 with mean 54= 56
For the left hand side we subtract 2 from means 50
50-2= 48
48-2=46
46-2= 44
