Answer: D. 8.25

Step-by-step explanation: A data set can be divided into 4 equal parts, called <u>Quartile</u>. A quartile divides the data into three points:

  • Lower quartile: Q1;
  • Median: Q2;
  • Upper quartile: Q3;

<u>Interquartile</u> <u>Range</u> (IQR) is a measure of variability based on data divided into quartiles or the measure of where the bulk of the values are.

To calculate interquartile range:

IQR = Q3 - Q1

The table shows Q1 = 27.825 and Q3 = 36.075, then

IQR = 36.075 - 27.825

IQR = 8.25

<u>The value of interquartile range is 8.25.</u>

April is randomly choosing five CDs to bring in her car from the following: 6 pop CDs, 8 rock CDs, and 10 R
Ymorist [56]

The complement of "April choosing five Pop CDs" is "Choosing five CDs where not all of them are Pop", making the second option a right choice.

In the question, we are given that April is randomly choosing five CDs to bring in her car from the following: 6 Pop CDs, 8 Rock CDs, and 10 R&B CDs.

We are asked what will be the complement of April choosing 5 Pop CDs.

The complement of a set is the one, where no element of the original set is present.

The original set is that "April is choosing 5 Pop CDs".

This means that April, while choosing 5 CDs from the given set, chooses all 5 CDs to be Pop.

While making the complement we need to change the final outcome.

To change this, we just need to make one exception to this, which can be achieved by making one other than Pop CD.

This gives us the set: "Choosing 5 CDs where not all of them are complement".

Thus, the complement of "April choosing five Pop CDs" is "Choosing five CDs where not all of them are Pop", making the second option a right choice.
