Find a confidence interval for μ assuming that each sample is from a normal population.
a. ¯x = 14, σ = 4, n = 5, 90 percent confidence
10.186 < u < 17.814
-------------------------------
b. ¯x = 37, σ = 5, n = 15, 99 percent confidence
33.157 < u < 40.843
-------------------------------
c. ¯x = 121, σ = 15, n = 25, 95 percent confidence
114.81 < u < 127.19
-------------------------------
