Suppose we know that the proportion of objects in a population that have a particular characteristic of interest is 0.10.Are there any concerns if we want to calculate probabilities for the sampling distribution of n = 40 using a normal approximation?
A) Because nis large, our only concern with using a normal approximation will be the small amount of variability in the sampling distribution of .
B) Because is small here, the sampling distribution of
should not be assumed to be approximately normal.
C) Because ≤ 0.5, the sampling distribution of
should not be assumed to be approximately normal.
D) If n < 5, then a normal approximation is not appropriate.
