Question

WILL MARK BRANILEST AND 40 POINTS

Answer 1

Step-1: Find the data.

⇒
`70, 80, 90, 90, 100, 100, 100, 110, 110, 110, 110, 120, 120, 120, 120, 130, 130, 140`

Step-2: Count the digits in the data

• ⇒ 18 digits

Step-3: Is the number of digits in the data odd or even?

• Even - - 2, 4, 6, 8, 10, 12, 14, 16, 18
• Odd - - 1, 3, 5, 7, 9, 11, 13, 15, 17, 19

The digits in the data set is even.

Step-4: Refer to the following

• Even: n/2th
• Odd: n + 1/2th

Step-5: Find which digit in the data is the median

18/2 = 9th

The 9th digit of the data is the median

Step-6: Find the median

`70, 80, 90, 90, 100, 100, 100, 110, \bold{110}, 110, 110, 120, 120, 120, 120, 130, 130, 140`

110 is the median.

Answer 2

median: 110

given data set:

70, 80, 90, 90, 100, 100, 100, 110, 110, **median**, 110, 110, 120, 120, 120, 120, 130, 130, 140

there are total 18 data's

the median will be between 9th and 10th data.

9th --> 110

10th --> 110

median:

( 110 + 110 ) ÷ 2

110
