Question

Suppose that a population parameter is 0.7 and many samples are taken from the population. If the size of each sample is 50, what is the standard error of the distribution of sample proportions? O A. 0.005 OB. 0.089 O C. 0.065 O D. 0.109​

Answer 1

0.065 / C

Explanation:

the square root of the population parameter times 1 - the population paramater, in this case 1 times 0.3 divided by the sample size

`√(0.7(1-0.7)/50)` =0.065 aka C
