Here the sample values given are 15, 24, 25, 29, 31, 36, 76, 73, 85, and 100.
00:26
And the sample mean x bar is equal to 55 .272727.
00:34
And sample standard deviation s is given as 33 .973.
00:43
We need to find the z score of 24.
00:48
Let mu equal to x bar.
00:51
Since sample mean is an estimate of the population mean, we can take this 55 .2727 as the estimate of mean and sigma can be estimated as s, which is equal to 33 .9473.

In order to find the set score, if a particular data set x, the corresponding equation is x minus mu by standard deviation...
