Question: Biology and Environmental Science Peregrine falcons were placed on the U.S. Endangered Species list in the 1970s. Their population dwindled primarily as a result of the introduction of new chemicals and pesticides. Although it may seem like a peculiar nesting area, there are many falcon pairs in the New York City area. The tall buildings and bridges provide lots of open space for hunting. These birds have a wingspan of 3.3 to 3.6 feet and weigh between 18.8 and 56.5 ounces. A random sample of 35 falcons was obtained and each was carefully weighed. The sample mean was x¯ = 47.3 ounces. Assume σ = 6.2 ounces.

a. Find a 95% confidence interval for the true mean weight of peregrine falcons.

b. Using your answer from part (a), is there any evidence to suggest that the mean weight is less than 48 ounces?
