Median of 10, 55, 34, 21
First we arrange number in ascending or descending
10, 21, 34, 55 in ascending.
Median is the middle number and this is between 21 and 34.
We find the average:
(21 + 34) /2 = 55/2 = 27.5
Median is 27.5.

Answer:
a. True
Step-by-step explanation:
We have been given a statement. We are asked to determine whether the given statement is true or false.
Statement: A normal distribution is symmetric; therefore the probability of being below the mean is 0.50 and the probability of being above the mean is 0.50.
We know that normal distribution is continuous probability distribution.
We know that the total area under a normal distribution curve is equal to 1. We also know that mean represents center of the normal distribution curve.
The half area will be below center and half area will be above center.
Since 0.50 is half of 1, therefore, the probability of being below the mean is 0.50 and the probability of being above the mean is 0.50 and given statement is true.
