Answer: 90% confidence interval would be
Step-by-step explanation:
Since we have given that
n₁ = 50
Number of metal tagged penguins survived = 10
So,
n₂ = 50
Number of electronic tagged penguins = 18
So,
So, at 90% confidence interval, z = 1.28
So, interval would be
Hence, 90% confidence interval would be
