Question

Need help with my homework please look at the picture.

Answer 1

Given the dot plot as shown below:

To evaluate the mean, we write out the data values as seen on the x-axis.

Thus, the data values are:

`2,4,4,4`

The mean is expressed as

`\frac{sum\text{ of individual values}}{total\text{ number of values}}`

Thus, the mean number of times Zach's teammates were late to practice last week is evaluated as

`\begin{gathered} (2+4+4+4)/(4) \\ =(14)/(4) \\ =3.5 \end{gathered}`
