the growing seasons for a random sample of 35 U.S. cities were recorded, yielding a sample mean of 190.7 days and a sample standard deviation of 54.2 days. Estimate the true mean population of the growing season with 95% confidence.
-----------------------
x-bar = 190.7
E = 1.96= 1.96*9.16147= 17.9565
E = 0.21394...
-----------------
CI is (190.7-17.9565.. ,190.7+17.9565...)
CI: 172.5295.. < mu < 208.4425..
