Question

random error in the Arithmetic mean of 15 observation is alpha then the random error is the Arithmetic mean of 150 observation would be​

Answer 1

Answer:

Explanation:

If we get to see an increase in the number of observations then the ultimate result would be that there would be a proper decrease in the error that occurs.

One of the rules that you have to keep in mind while performing the calculations is that the number of observations when multiplied by the error results in a constant result.

For instance if there were n1 e1 then it would equal to n2 e2.
