50% of data will be less than 50
Step-by-step explanation:
A normal distribution has the shape of the graph like a bell.
Given
we have to find how much data will be less than 50.
So we have to calculate z-score for 50.
The z-score is zero. As we have to find the number of values less than 50 we will find the area to the left of curve
In order to convert the probability into percentage
=0.50*100
=50%
Hence,
50% of data will be less than 50
Keywords: Probability, Area under the curve
