Question

Find the mean of the cursors in the table to the rightValue Frequency855124153The mean isRound to the nearestent)

Answer 1

11.0582

1) Analyzing that table, we can find out the mean by adding the frequencies on the numerator over the number of observations as the bottom number:

`\begin{gathered} (8+8+8+8+8+11+11+11+11+11+12+12+12+12+15+15+15)/(17) \\ (188)/(17)=11.0582 \end{gathered}`

Note that each frequency indicates how many times that value occurs. Also adding it up the column of frequencies we have the total number of observations.

2) Hence, the answer is 11.0582
