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

Answer:

0.005

Step-by-step explanation:

To get the standard deviation of the sample proportion, we will use this formula - std = √p (1 - p) / n Replace the variables with the given values, then simplify. std

√ 0.7 ×(1 - 0.7) / 50

0.83660027 × 0.3/50

= 0.00501960162
