For full marks your answer should be accurate to at least two decimal places.
The marking allows the use of the finite population correction factor, and will provide appropriate feedback if the student did make use of it.
I already founds the population mean and the population standard deviation, the only thing i need to find is the following:
- The standard deviation of sampling distribution
The standard deviation of the sample mean is given by
σ(x-bar) = σ/√n (where σ is the population standard deviation and n is the sample size).
However, if the sample size is a large proportion of the population size, the finite population correction factor is applied, and the formula is then
σ(x-bar) = (σ/√n ) x √ { (N – n) / (N – 1) }
where N = population size and n = sample size
So in this case you will have
σ(x-bar) = (σ / √ 2) x √ (2 / 3)
