QUESTION
The mean of 100 observations is 50. If one of the observation which was 50 is replaced by 150 then what will be the resulting mean?​

Answer 1

Answer:

51

Step-by-step explanation:

Let the total of 100 observations be x

so X/100= 50

x= 5000

if 50 is replaced by 150 then the new total is 4950+ 150 = 5100

• new mean = 5100/100= 51
