The mean of 30 observations recorded in an experiment is 5. lf the observed largest value of 34 is deleted, find the mean of the remaining observations
The mean of 30 observations recorded in an experiment is 5. lf the observed largest value of 34 is deleted, find the mean of the remaining observations
Answer Details
The mean of the 30 observations is given as 5. If we remove the largest observation of 34, we will be left with 29 observations. To find the mean of the remaining observations, we need to sum them up and divide by the number of observations.
The sum of the 30 observations is 30 x 5 = 150. If we remove the observation of 34, the sum of the remaining 29 observations will be 150 - 34 = 116.
Therefore, the mean of the remaining 29 observations is 116/29 = 4.
Hence, the answer is 4.
