For this problem, we are told that below are the jersey numbers of 11 players randomly selected from a football team.
00:06
We're asked to find the range variance in standard deviation.
00:10
And we're asked, what do the results tell us? so, first of all, it looks like our lowest value is 11, and our greatest value is 95.
00:20
Less, less, less, less, less, less, less, less, less, less, less, less, less, less, less, and also more, more, more, more, more, more, more, more.
00:28
Okay, yes, so 11 is the minimum.
00:30
95 is the maximum, so the range is going to be 95 minus 11 or 84.
00:37
To find the standard deviation, the first thing that we want to do is actually find the mean value, x bar.
00:43
It's going to be found by taking the sum of all of our numbers...
