In this question, we have been given that every three salaries for 7 emploss of small businesses are given below.
00:08
So we have taken 7 of holes, therefore m value will be equal to 7.
00:12
And the data values are as follows, 715, 766, 775, 875, 875, 933 and 974.
00:23
So it is given that.
00:25
Suppose if we change from $9 .74 salary, to 771.
00:34
That is the last value has been changed.
00:36
So what happens to the mean? so we will observe that.
00:43
First, we find the mean for original data, the mean for original data.
00:52
So mean is calculated as sum of observations divided by number of observations.
00:57
So 715 plus 766 plus 775 plus 871 plus 871 plus 890.
01:05
933 plus 974 divided by 7.
01:10
So on calculating this, we get the mean for original data as $847...
