Question

The graph represents a distribution of data.

A graph shows the horizontal axis numbered 35 to x. The vertical axis is unnumbered. The graph shows an upward trend from 35 to 50 then a downward trend from 50 to 65.

What is the mean of the data?

5
10
30
50

Answer 1

50

Explanation:

Answer 2

Mean=50

Explanation:

The mean of a probability distribution is a measure of central tendency,and gives information about how the possible values of x are distributed.

The vertical axis measures the probability of finding a specific value of x in the sample. The probability of finding a value near the mean is high (that is why the value of the function that is depicted in the vertical axis, increases as we get closer to the mean=50): this is because the mean is that value of x around which higher probability of occurrence is associated.
