Standard deviation error= 3 for the average of the 36 draws from the 0-1 box.
Standard deviation error: The standard error of the mean, or simply standard error, indicates how different the population mean is likely to be from a sample mean. It tells you how much the sample mean would vary if you were to repeat a study using new samples from within a single population.
In the question it is said to find the standard error of the average of 36 draws from 0-1 box,
Probability is, number of outcomes(n)/total number of events(t)
Probability,σ= 36/2=18
σ=18, n=36 from above
Standard deviation error= σ/[tex]\sqrt{n}[/tex]
=18/[tex]\sqrt{36}[/tex]
=18/6 =3
therefore, standard deviation error= 3.
