For the past fifty-two Friday evenings it has taken me an average 
of 10 rounds of sakau with a standard deviation s of 3 rounds
of sakau for me to get sakaula. The sample size n is 52. Note that it is more than
30. Use this data to construct a 95% confidence interval for the population mean m number of rounds of sakau required for me to become sakaula.
| Statistic | Equation |
|---|---|
| Calculate a confidence interval for a mean m for large n (n>30) using the population deviation s |  |
| Calculate a confidence interval for a mean m for large n (n>30) using the sample deviation s |  |
| Confidence interval for m and s for n < 30. |  |
