so that would mean 2+3=3+2
all you do is move the numbers around to get the same answer.

Lady_Fox [76]

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

$
Var(\hat p)=\frac{p*(1-p)}{n}
$

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 $E(\hat p)=p
$

which does not affect the value of n ( sample size).
