Question

1.Find the mean of the data and round to the nearest hundredths.

2.Which reflects the best measure of the center?

Answer 1

Explanation:

Mean of the data is defined by the average of the data.

Mean =
`\frac{\text{sum of the data}}{\text{Number of terms}}`

=
`(28+32+65+159+22+20+33)/(7)`

=
`(359)/(7)`

= 51.29

Term at the center of the data when arranged in the increasing order is called as Median of the data.

20, 22, 28, 32, 33, 65, 159

Answer is MEDIAN

Median of the given data is 32.
