Question

Which of the following describes the probability distribution below?
A. Median is greater than the mean and the majority of data points are to the left of the mean.
B. Median is greater than the mean and the majority of data points are to the right of the mean.
C. Mean is greater than the median and majority of data points are to the left of the mean
D. Mean is greater than the median and majority of data points are to the right of the mean

Answer 1

Answer:

B. Median is greater than the mean and the majority of data points are to the right of the mean.

Step-by-step explanation:

Mean = sum(x × p(x))

= (1×0.1)+(2×0.15)+(3×0.2)+(4×0.45)+(5×0.1)

= 3.3

Probability of more than 3.3 is:

0.45 + 0.1 = 0.55 > 0.5
