I want to know what is the 90% confidence interval is

Question 5 of 11 0/1 A study was designed to test whether applying metal tags is detrimental to a penguin. One variable examined is the survival rate 10 years after tagging. The scientists observed that 10 of the 50 metal tagged penguins survived, compared to 18 of the 50 electronic tagged penguins. Construct a 90 % confidence Interval for the difference in proportion surviving between the metal and electronic tagged penguins ( PM - PE). Let pyr be the proportion of penguins with metal tags that survived and PE be the proportion of penguins with electronic tags that survived. Round your answers to three decimal places. The 90% confidence interval is i 0,36 i 0.95 eTextbook and Media Hint Assistance Used If we have large samples of sizes /, and ng from two different groups, we can construct a confidence interval for p, - P2. the difference in proportions between the two groups, using (P1 - P2 ) + 2" . 1 PI (1 - PI) P2 (1 - P2) where p, and p, are the proportions in the respective samples and z" is a standard normal endpoint to give the desired level of confidence, To ensure that the sample size is large enough in each group, we check that mp, 2 10 and m (1 - p, ) 2 10 and that nap2 2 10 and n2 (1 - P2) 2 10.
