After the researchers see the number of subjects they will have to interview, they reexamine their criteria. The researchers could decrease the number of subjects while having the least impact on the reliability of the study by .A. increasing p and decreasing B.
B. increasing p or decreasing B.
C. decreasing p and increasing B.
D. decreasing p or increasing B.

D. decreasing p or increasing B.

Explanation:

From the formula presented for the sake of answering this question as shown below:

n = Np (1-p)/ (N-1)B squared/4 + (p) (1-p)

Hence, the number of subjects can be reduced while having the least impact of the study reliability if we decrease the proportion of subjects needed (p) or increase the acceptable amount of error (B). This way, the study still remains reliable.

the aorta is the large artery leaving the heart branches into smaller arteries, which eventually branch into capillaries.the arteries carry oxygen and nutrients away from your heart, to your body's tissues. the capillaries are small, thin blood vessels that connect the arteries and the veins. the statement that arteries carry oxygen-rich blood to capillaries is true. veins on the other hand are blood vessels that take oxygen-poor blood back to the heart.
