The data in this quiz is from page nine of the College of Micronesia-FSM Space Utilization and Facilities Master Plan Study, Part 3 - Detailed Report for the National Campus . Note that this data is actually time trend data and should more properly be analyzed as trend line data. That said, a confidence interval analysis of the mean can be constructed. The headcount data is for fall terms at the national campus from 2004 to 2013.

1. n = _________ Determine the sample size n for the data.
2. x = _________ Determine the sample mean x for the data.
3. sx = _________ Determine the sample standard deviation sx for the data.
4. SE = _________ Calculate the standard error of the mean for the lap times data.
5. df = _________ Calculate the number of degrees of freedom.
6. t_c = _________ Calculate t_critical using a confidence level c of 95%
7. E = _________ Calculate the margin of error for the mean E.
8. p(__________ ≤ μ ≤ __________) = 0.95 Calculate the 95% confidence interval for the population mean headcount μ.
9. __________ Page 9 of the Beca College of Micronesia-FSM Space Utilization and Facilities Master Plan Study, Part 3 - Detailed Report for the National Campus projects an average headcount of 1136 in 2018. Is 1136 within the 95% confidence interval for the population mean?
10. _________________ Would you reject OR fail to reject 1136 as a possible population mean based on the data and analysis?
