Use the given degree of confidence and sample data to construct a confidence interval for the population proportion p.

A study involves 607 randomly selected deaths, with 35 of them caused by accidents. Construct a 98% confidence interval for the true percentage of all deaths that are caused by accidents.

Solution

3.33%<p<8.21% is the answer

Sample proportion = 0.05709

Z value for 98% = 2.33

sigma^2 = p(1-p)/n
