Question
Find the z-score of each measurement in the following sample data set.$$\begin{array}{lllll}1.6 & 5.2 & 2.8 & 2.7 & 4.0\end{array}$$
Step 1
The mean is calculated by adding all the numbers in the data set and then dividing by the number of values in the set. So, the mean (μ) is: $$ \mu = \frac{1.6 + 5.2 + 2.8 + 2.7 + 4.0}{5} = 3.26 $$ Show more…
