In 1995, there were 85 rabbits in Central Park.

The population increased by 12% each year. This

relationship can be represented by the function

f(x) = 85(1.12). What would be an appropriate

domain and range for this problem situation?

What is the perimeter of a rectangular building that is 80 feet wide and 140 feet deep?

An automobile assembly line operation has a scheduled mean completion time, μ, of 12 minutes. the standard deviation of completion times is 1.6 minutes. it is claimed that, under new management, the mean completion time has decreased. to test this claim, a random sample of 33 completion times under new management was taken. the sample had a mean of 11.2 minutes. assume that the population is normally distributed. can we support, at the 0.05 level of significance, the claim that the mean completion time has decreased under new management? assume that the standard deviation of completion times has not changed.
