Answer:
50.7
Step-by-step explanation:
According to the question mean of 100 items is = 46
Sum of 100 items = 46×100 = 4600
Misread 61 instead of 16 and 34 instead of 43
∴ Difference = (61 + 34) - (16 + 43) = 95 - 59 = 36 (more)
∴ Actual sum = 4600 - 36 = 4564
Now total observations are = 90
∴ Actual average = 4564/90=50.7
