The answer for question 4 is C and the answer for question 5 is D.
The mean and standard deviation of the x sampling distribution for each of the following sample sizes will be .
Suppose X has a distribution with mean and standard deviation
then,
the distribution of the mean of samples of size n, drawn from the values of X, is normally distributed with a mean equal to the mean of X, and a standard deviation equal to
Symbolically, we write it as:
A random sample is selected from a population with a mean = of 100 and a standard deviation = of 10.
