Question 437869
 A study was done to determine the average number of homes that a homeowner owns in his or her lifetime. For the 50 homeowners surveyed, the sample average was 3.8 amd the sample standard deviation was 1.5. calculate the 95% confidence interval for the true average number of homes that a person owns in his or her lifetime. 
------------------
x-bar = 3.8
ME = zs/sqrt(n) = 1.96 * [1.5/sqrt(50)] = 0.4158
----
95% CI: 3.8-0.4158 < u < 3.8+0.4158
95% CI: 3.3842 < u < 4.2158
