Question

Mean of 100 observatin is 40. If one of the observation is 50 and if we replace it by 60. What is the resulting mean

Answer 1

Answer:

41.1

Step-by-step explanation:

Mean of 100 observation = 40

Sum of 100 observation = 40*100=4000

If one observation of 50 is replaced by 6

then sum=4000+10=4110

New mean=4110/100

=41.1
