Question

Find the mean and median of the given data:

64, 41, 43, 127, 99, 61, 92, 71, 58 and 57

If 58 is replaced by 85, what will be the new median.​

Answer 1

Answer:

Mean= 71.3

Median= 80

New median= 67.5

Step-by-step explanation:

64, 41, 43, 127, 99, 61, 92, 71, 58, 57

Ascending order: 41, 43, 57, 58, 61, 64, 71, 92, 99, 127

mean= (41+43+57+58+61+64+71+92+99+127)/10

= 713/10= 71.3

Median= (99+61)/2

= 160/2

=80

New ascending order: 41, 43, 57, 61, 64, 71, 85, 92, 99, 127

New median= (64+71)/2

=135/2

=67.5

That's all
