Question

HELPPPP FIRST GET BRAINLLEST Measure the difference between the lower quartile of Data Set A and the lower quartile of Data Set B. Round to the nearest tenth when performing all operations.

Answer 1

Answer:

26

Step-by-step explanation:

Let's find first the lower quartile in both A and B

steps:

1. look for the smallest sum of two consecutive numbers
2. divide by 2 to get the lower quartile

• A

73 and 75 are the smallest consecutive numbers

• 73+75 = 148
• 148/2 =74

The lower quartile in A is 74

• B

47 and 49 are the smallest consecutive numbers

• 47+49 = 96
• 96/2 = 48

The lower quartile in B is 48

• 74-48 = 26

Answer 2

Answer:

29

Step-by-step explanation:

To find the lower quartile of each you need to find the median to split them into 2 groups (upper and lower quartile).

Lower quartile of Set A: 73, 75, 79, 81, 84, 85

Lower quartile of Set B: 47, 49, 51, 51, 55, 56

Now you find the median of the 2

Set A: 80

Set B: 51

Lastly you subtract A & B and get 29
