We are interested in the mean length of adult largemouth bass in
a lake. We collect 100 of these fish randomly and measure their
lengths (in cm). At the end we compute a 90% confidence interval of
(40, 45) for the mean. What can we conclude?
90 out of 100 fish in the sample have lengths between 40 cm and
45 cm.
There is a 90% chance that the mean length of largemouth bass in
this lake lies between 40...

A large tank of fish from a hatchery is being delivered to a
lake. The hatchery claims that the mean length of fish in the tank
is 15 inches, and the standard deviation is 6 inches. A random
sample of 31 fish is taken from the tank. Let x be the mean sample
length of these fish. What is the probability that x is within 0.5
inch of the claimed population mean? (Round your answer to four
decimal places.)
