Answer
Answer B
Work Step by Step
The mean of $n$ numbers is the sum of the numbers divided by $n$. The median of $n$ is the middle number of the numbers when they are in order (and the mean of the middle $2$ numbers if $n$ is even). The mode of $n$ numbers is the number or numbers that appear(s) most frequently.
Hence here the mean is: $\frac{384+480+576+640+768}{5}=569.6$. The median is the mean of the middle items in the sequence $384,480,576,640,768$, which is: $576$.
We can see that the median is greater than the mean.
The range is the difference between the largest and the smallest data value. The range is: $768-384=384$
Hence, the correct answer is B.
