Suppose a sample of size 50 has a sample mean of 20.In this case,the sum of all observations in the sample is 1,000.
Sample Mean
The average value of a sample set of numbers, calculated by adding all the observations and dividing by the number of observations.
Observations
Data points or values recorded during an experiment or study.
Sample
A subset of individuals, items, or data from a larger population used to estimate characteristics of the whole population.
- Calculate the sum of observations given the sample size and mean.

Final Answer :
True
Explanation :
To find the sum of all observations in a sample, we need to multiply the sample mean by the sample size. Therefore, if the sample size is 50 and the sample mean is 20, the sum of all observations would be 50 * 20 = 1,000.
