Answer:
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.
I think the answer is C .
