Answer:
Mean = 6.2
Explanation:
The times recorded during the experiment are:
[tex]undefined[/tex]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.
[tex]\begin{gathered} Mean=\frac{Sum}{Number\text{ of items}} \\ =\frac{7.2+6.3+6.9+4.1+6.3+6.4}{6} \\ =\frac{37.2}{6} \\ =6.2 \end{gathered}[/tex]The mean is 6.2 seconds.
