Answer #1

Solution:

We are given that: t he probability that a randomly selected diabetes patient needs medical attention is 0.08.

Thus p = 0.08

We have to find the the minimum sample size required to ensure that the sampling distribution of sample proportion of diabetes patients who need medical attention is approximately normal.

Sampling distribution of sample proportion is approximately normal when following condition are holds.

Thus the minimum sample size is n = 136 required to ensure that the sampling distribution of sample proportion of diabetes patients who need medical attention is approximately normal.
