Question

Suppose a random sample size of 34 is obtained from a population with population mean 30 and population standard deviation 4.
What is the shape of the sampling distribution of the sample average?
a) unknown shape
b) bell shaped
c) block shaped
d) horn shaped

( don't Hand writing solution)

Definition Definition Number of subjects or observations included in a study. A large sample size typically provides more reliable results and better representation of the population. As sample size and width of confidence interval are inversely related, if the sample size is increased, the width of the confidence interval decreases.
