Question

Find the mean of the data.Second part: Magazine subscription sold this week 3,6,7,6,7,9,11

Answer 1

the mean of a set of numbers can be calculated by adding all values in the set and then dividing the sum by the number of values added.

So we have:

`\begin{gathered} mean=(2+5+4+5)/(4) \\ mean=(16)/(4) \\ mean=4 \end{gathered}`

Therefore the mean is 4.

For the magazine set of data, we have 7 values, so the mean is:

`\begin{gathered} mean=(3+6+7+6+7+9+11)/(7) \\ mean=(49)/(7) \\ mean=7 \end{gathered}`

Therefore the mean is 7.
