What is the interquartile range of this data?

6

7

8

9

Step 1: Find Q2

Note - Q2 is basically the median of the set

We see that the two numbers in the middle are 28 and 32.

To get the median, find the average of 28 and 32.

28 + 32 = 60, 60/2 = 30

Q2 = 30

Step 2: Find Q1

The median splits the set. So anything before 30, is what we should focus on.

In this case, it's: 12, 16, 20, 24, and 28

Find the median of those five numbers. We get: 20

Q1 = 20

Step 3: Find Q3

Similar to before, focus on the numbers after 30.

In this case, it's: 32, 36, 40, 44, 48

Find the median of those five numbers. We get: 40

Q3 = 40

Step 4: Find the IQR

The IQR (Interquartile Range), as shown in its name, is found by subtracting Q3 and Q1.

Q3 - Q1 = 40 - 20 =20

IQR = 20

20

every 5 customers that walk in, only 2 buy popcorn.

step-by-step explanation:

basically 2/5.

brainliest would be appreciated.

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%
