A laboratory tested 70 chicken eggs and found that the mean amount of cholesterol was 228 milligrams with s = 12 milligrams. Construct a 95 percent confidence interval for the true mean cholesterol content, μ, of all such eggs.
---------------------------
sample mean = 228
---
Max Error = E = (invT(0.975 with df = 69)
= 1.9949*1.4343
= 2.86
---------------------
95% CI: 228-2.86 < u < 228+2.86
