Answer 1

the answer is c

Explanation:

I got a 100 in the test

Answer 2

So then the accumulated % between the first quartile and the upper quartile would be:

75%- 25% = 50%

And the difference between the upper Q3 and lower quartile Q1 is represented by the interquartile range defined as:

`IQR= Q_3 -Q_1`

Explanation:

We need to remember that we have a quartile by definition is a "type of quantile which divides the number of data points into four more or less equal parts, or quarters".

The first quartile Q1 (lower quartile) accumulates 25% of the data below.

The first quartile Q2 (median) accumulates 50% of the data below.

The third quartile Q3(upper quartile) accumulates 75% of the data below.

So then the accumulated % between the first quartile and the upper quartile would be:

75%- 25% = 50%

And the difference between the upper Q3 and lower quartile Q1 is represented by the interquartile range defined as:

`IQR= Q_3 -Q_1`
