Mean Height Calculation from Sample Data

Medium Preparing For Higher Math Statistics And Probability

A researcher collected data on the heights (in inches) of a random sample of 10 adult males. The heights were:

65, 67, 70, 70, 72, 74, 75, 76, 78, 80

Using this data, calculate the mean height of the sampled individuals.

Recall that the mean is calculated by summing all the values and dividing by the number of values.

$$69.5$$

$$71.5$$

$$72.0$$

$$73.0$$
