1. (3 pts) A simple random sample of $n = 44$ adult male Gnus from the ACME White-tailed Gnu Farm is surveyed. The sample mean weight of the Gnus is $\bar{x} = 390$ lbs, with a standard deviation of $s_x = 93$ lbs. Find a 99%-confidence interval for the mean weight of all adult male Gnus on the ACME Farm.

The weights at birth of five randomly chosen baby giraffes were 111, 115, 120, 103, and 106 pounds. Assume the distribution of weights is normally distributed. Find a 95% confidence interval for the mean weight of all baby giraffes. The summary statistics: x̄ = 111, s = 6.819090848 pounds. Use the Table in Appendix to solve this problem. Round to the nearest tenth of a pound. Show your work.
