Answer:
A. exactly 0.50
Step-by-step explanation:
We have been given a statement. We are asked to choose the correct option about given statement.
We know that every histogram has 5 points summary.
1st point is known as minimum point, 2nd point is first quartile, 3rd point is median, 4th point is upper quartile and 5th point is maximum point.
In a normal distribution 25% of the data points are to the left 1st quartile, 50% of the data points are to the left of median and 75% of the data points are to the left 2nd quartile.

Therefore, exactly 0.50 of the total area which must be to the left of the median.
