Answer:
51
Step-by-step explanation:
mean =50
=x/100
where x=total sum of observations
so x=5000
reducing 50 from x and adding 150 to x
so new x=5000-50+150
=5100
mean=5100/100
=51

Answer:
51
Step-by-step explanation:
Total value of 100 observations = (100 * 50) = 5000
New value of observations = 5000 - 50 + 150 = 5100
Hence resulting mean = 5100 / 100 = 51
