MATH 201 Course Project deliverable 3. Confidence interval e Name: Question 1. Using the provided Excel worksheet, 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. (50 pts) Lower limit: Upper limit: Question 2. Interpret the above confidence interval(s) in 50-100 words. (20 pts) Question 3. If you have one sample group, determine whether the value in your research question (the value which is compared to the population mean) is within the confidence interval or not. Then describe what it implies. If you have two groups of data, determine whether the confidence intervals of the two groups overlap or not. Then describe what that implies. (50 100 words) (25 pts) \f
