On the board, your teacher writes an example of how to find the median. one of the numbers is erased, leaving what is shown. which choice could be true?

17, 20, 30, 28, 18

median=24

a 12
b 22
c 24
d 34

Solution:

Median = Mid value of Set of observation

If number of observation is odd, suppose n

Median = th term

If number of observation is even , then

Median = Mean of two middle observation i.e

Data set : 17, 20, 30, 28, 18

Data arranged in ascending order: 17,18,20,28,30

Let one data =x

Number of observation is even.

Given, Median = 24

As , when number of observation is even , median is mean of two mid values.

Median=→→→ getting the median.

So, x must be greater than 30.

The correct option satisfying the above condition is Option (D) 34.

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

3/6 chance

step-by-step explanation:

half of the nubers are odd numbers (1,3,5) which in that case if you would be told to simplify it would be 1/2
