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

For easier comparison, convert all amounts to grams:
30 oz * 28.3 grams = 849 grams
1.6 lb * (16 oz/1lb) * (28.3 grams) = 724.48 grams
800 grams
Comparing the three quantities, the highest is 30 oz (849 grams); next is 800 grams, then 1.6 lb (724.48 grams)
