Question

Suppose that you and 100 other people ask 25 randomly selected workers how much money they spent on lunch. Which of the following statements would be true?

a) All samples would result in the same sample

    mean.

b) All samples would results in slightly different

    sample means.

Answer 1

The correct option Is :

b) All the samples would result in slightly different sample means.

Reason: Since in this survey, Each people survey 25 randomly selected workers,there maybe samples in which few of the workers would have a higher paygrade than the others or lower paygrade than the others as a result of which the sample mean income of that particular sample may be higher or lower and the data collected from each sample of 25 randomly selected workers would not yield in same sample means because of the presence of outliers,i.e,a certain worker may have a higher pay or a lower pay hence affecting the other data collected in the sample. So the sample means of those different samples would not be the same.
