In this problem, we are given a sample, and this includes the values, and they are 54, 55, 68, then we have 57, 48, 68, 63, followed by 35, then we have 60, 46, 55, 43, followed by 42, 60, then we have 67.
00:25
After that we have 39 appearing twice, then we have 55, 52, 51 and 62.
00:32
And we have to determine the value of the standard deviation of this sample.
00:37
So we will represent that with the symbol sigma, and that's what we have to get.
00:41
So first we count, and we see that the size of the sample, that is 20...
