Using JMP, calculate the 95% confidence interval of the population mean for each group and report the lower limit and upper limit of the interval. If your research question is to test the population mean against a single value, you have only one group. If your research question is to compare the population mean of two groups, you have two groups. Refer to JMP Learning Library, Basic Inference - Proportions and Means/ One Sample t-test and CI (video or one-page guide). (40 %) Lower limit: Upper limit:

Interpret the above confidence interval(s) in words. (20 %)

If you have two groups of data, determine whether the confidence intervals of the two groups overlap or not. Then describe what it implies. (50 - 100 words) (25 %)

Attach the JMP output to this report. (10 %)
