Okay, so i see that you need help with this problem and you need to find the range, the mean, the variance, and you need to interpret the results.
00:10
So it says, calculate the range arithmetic mean, variance, and interpret the statistics.

During last weekend's sale, there were five customer service reps on duty at the electronic superstore.
00:22
The numbers of hd tvs, these representatives sold.
00:27
So one sold five, one sold eight, one sold four, one sold ten, and one sold three.
00:32
So the range, you're going to take the smallest from the largest, and that is seven.
00:39
The mean, if you add up all of these numbers, you're going to get five plus eight, plus four, plus ten, plus three.
00:57
So that would be 30, and then dividing that by five, and the mean is six.
01:03
And then the variance.
01:05
So if i subtract or find the difference, 6, 6, and 6.
01:16
So then that would be 3 squared, 4 squared, 2 squared, 2 squared, 2 squared, and 1 squared, 1, 4, 16, and 9...
