    A sample of 40 observations is selected from one somewhat normal population. The sample mean is 102 and the sample standard deviation is 5. A sample of 50 observations is selected from a second source. The sample mean was 99 and the standard deviation was 6. Conduct a test of the hypothesis using the .04 level of significance.

    Solution Summary

    The solution conducts a test of hypothesis of difference between means. It determines the significance level, z statistic, and observed difference in order to reject or fail to reject the null hypothesis. An Excel file is used.
