blood disorder found 4 out of 500 people had genetic markers for it. (a) Construct a 90% confidence interval for actual proportion of people with this genetic marker. (note: your number of successes is very low here) (b) Construct a 99.9% confidence interval for actual proportion of people with this genetic marker. (note: your number of successes is very low here) (c) How many people would we need to sample for this interval to have maximum width of 0.02 assuming the probability of success stays VERY low. Assume 99.9% confidence still and no prior knowledge of the true proportion except is is very low.

Question
5. A recent investigation into a rare blood disorder found 4 out of 500 people had genetic markers
for it.
(a) Construct a 90% confidence interval for actual proportion of people with this genetic
marker. (note: your number of successes is very low here)
(b) Construct a 99.9% confidence interval for actual proportion of people with this genetic
marker. (note: your number of successes is very low here)
(c) How many people would we need to sample for this interval to have maximum width of
0.02 assuming the probability of success stays VERY low. Assume 99.9% confidence still
and no prior knowledge of the true proportion except is is very low.
(d) Were any assumptions needed to answer the above questions. Why or why not?
