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:

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
