Answer:
Step-by-step explanation:
As sample size increase the variability of the estimate of the proportion would decreases ( reduces)
The formula of variance of the estimator of the proportion is as
Since the denominator of the formula of the variance of sample proportion is n
so as n increase the variance of it decrease.
The center of the estimate of proportion would same
Because
which does not affect the value of n ( sample size).
