Question

One of the students data was removed from the survey in the previous question and replaced with a different students data

Answer 1

The Solution:'

The given data is:

`0,0,0,0,0,0,0,1,1,1,1,2,2,2,2,2,2,2,3,3,3,3,4,5,9`

We are required to find the minimum, maximum, first quartile, third quartile, and median.

Step 1:

The total number of data is 25.

`N=25`

The minimum = 0

The maximum = 9

The first Quartile is

`Q_1=((N+1)/(4))\text{th}=((25+1)/(4))th=(26)/(4)th=6.5th\Rightarrow0`

6.5th means the number in the 6.5th position when the data is arranged in ascending order.

The third Quartile is

`Q_1=(3)/(4)(N+1)\text{th}=(3)/(4)(25+1)th=(3*26)/(4)th=19.5th\Rightarrow3`

The median is

`Q_1=((N+1)/(2))\text{th}=((25+1)/(2))th=(26)/(2)th=13th\Rightarrow2`

Therefore, the correct answers:

min=0,max=9, first Quartile=0, third Quartile=3, median=2.
