From a population of 200,000,000 elements, the standard deviation is known to be 14. A sample of 49 elements is selected. It is
determined that the sample mean is 56. The standard error of the mean is
1 answer:
Answer:
The standard error of the mean = 2
Step-by-step explanation:
Given that:
The standard deviation σ = 14
The sample size n = 49
The sample mean = 56
The formula for calculating the standard error can be expressed as:
S.E = 2
Therefore, the standard error of the mean = 2
