a random sample of 19 rainbow trout caught at Brainard Lake, Colorado, had mean length x=11.9 inches with sample standard deviation s=2.8 inches. Find a 99% confidence interval for the population mean length of all rainbow trout in this lake
----------------
x-bar = 11.9
ME = 2.5758*2.8/sqrt(19) = 1.6546
--------
99%CI:: 11.9-1.6546 < u < 11.9+1.6546
-----------
