Multiple Choice
Commercial fisherman working certain parts of the Atlantic Ocean sometimes find their efforts being hindered by the presence of whales. Ideally, they would like to scare away the whales without frightening the fish. Experience has shown that whales leave the sight of a fishing boat 40% of the time. One of the strategies being experimented with is to transmit underwater the sounds of a killer whale. On the 52 occasions that this technique has been tried, it worked 24 times (that is, the whales immediately left the area) .
-A 99% confidence interval for is (0.29, 0.65) . How would you interpret this interval?
A) When underwater sounds of killer whales are transmitted, we are 99% confident that whales leave the sight of a fishing boat 46% of the time.
B) When underwater sounds of killer whales are transmitted, we are 99% confident that whales leave the sight of a fishing boat between 29% and 65% of the time.
C) 99% of whales will leave the sight of a fishing boat if they hear sounds of a killer whale.
D) If we collect another sample of 52 occasions, there is a 99% chance that the sample proportion of whales who leave the sight of a fishing boat will be between 0.29 and 0.65.
