Question

The mean of 45 observations is computed as 29.75. If a value 37 is excluded from the data. Find the mean of remaining observations.

Answer 1

Answer:

29.58

Step-by-step explanation:

Mean = Sum of terms / No. of terms

29.75 = S / 45

S = 1338.75

After excluding 37, we have

S = 1301.75

Now, we have 44 terms instead of 45

So,

Mean = 1301.75/44

= 29.58
