Question

The mean is? round to one decimal place as needed

Answer 1

Mean = 6.2

Explanation:

The times recorded during the experiment are:

7.2, 6.3, 6.9, 4.1, 6.3, 6.4

To find the mean time, add the times together and divide by 6.

`\begin{gathered} Mean=\frac{Sum}{Number\text{ of items}} \\ =(7.2+6.3+6.9+4.1+6.3+6.4)/(6) \\ =(37.2)/(6) \\ =6.2 \end{gathered}`

The mean is 6.2 seconds.
