Question

find the mean and median of the data 35, 48, 92, 76, 64, 52, 51, 63 and 71. If 51 is replaced by 66 then what is the new median?

Answer 1

Mean = sum of all the observations / total number of observations
= 35+48+92+76+64+52+51+63+71/9
= 476/9= 52.8888889
Median

Ascending order

35,48,51,52,63,64,71,76,92

Median = mid value = 63

New data = 35,48,52,63,64,66,71,76,92 ( ascending order )

New Median = mid value = 64

Answer 2

Answer:

Step-by-step explanation:

Mean = sum of all the observations / total number of observations

= 35+48+92+76+64+52+51+63+71/9

= 476/9= 52.8888889

Median

Ascending order

35,48,51,52,63,64,71,76,92

Median = mid value = 63

New data = 35,48,52,63,64,66,71,76,92 ( ascending order )

New Median = mid value = 64
