Question

what is the mean? 43, 301, 73, or 52what is the median? 39, 43, 73, or 52what is the mode? 52, 73, 43, or 39what is the range? 73, 39, 52, or 43

Answer 1

The mean is calculated by the formula

`\bar{x}=(\sum ^n_(i\mathop=1)x_i)/(n)`
`\begin{gathered} \bar{x}=(33+52+52+39+84+30+11)/(7) \\ \bar{x}=(301)/(7) \\ \bar{x}=43 \end{gathered}`

The median can be found by rearranging the data from least to greater and the median will be the data exactly in the middle

`11-30-33-39-52-52-84`

the median is 39.

The mode is the date that repeats more time over the data set, in this case the only one that repeats itself is 52.

the mode is 52.

Finally, the range is the difference between the smaller value

`\begin{gathered} 84-11 \\ 73 \end{gathered}`

the range is 73.
