During the semester, all the students in a statistics class kept track of the number of mailings they received from a predatory

Verdich [7]

Answer:

The first step on this case is order the dataset on increasing way, and after do this we got:

11 14 15 16 17 17 18 19 21

We have a sample size of n =9

And in order to find the 75th percentile we need to find the position for this percentile with this formula:

$n_{75} = 0.75* 9= 6.75\approx 7$

So then we can conclude that the 75th percentile would be approximately on the 7 position of the dataset ordered and we got:

$x_{75} = 18$

Step-by-step explanation:

For this case we have the following data:

16 17 11 21 15 14 17 18 19

The first step on this case is order the dataset on increasing way, and after do this we got:

11 14 15 16 17 17 18 19 21
