Savatey [412]

Using the concepts of the mean and of the median, it is found that the correct option is given by:

both in the interval 6–10.

<h3>What are the mean and the median of the data-set?</h3>

  • The mean is the <u>sum of all observations divided by the number of observations</u>.
  • The median is the measure that separates the bottom half of the variable from the upper half, that is, the 50th percentile.

To calculate the mean from the histogram, we take the midpoint of each interval and calculate the weighed mean, hence:

M = \frac{14(3) + 9(8) + 5(13) + 2(18)}{30} = 7.17

The median is in the interval in which the 30/2 = 15th measure is, which is also in the interval 6-10, as the interval 1-5 had 14 adults, and after interval 6-10, there are 23 adults.

Hence, the correct option is given by:

both in the interval 6–10.
