Use the given degree of confidence and sample data to construct a confidence interval for the population mean. Assume that the population has a normal distribution.
The football coach randomly selected ten players and timed how long each player took to perform a certain drill. The times (in minutes) were: 7. 2, 10. 5, 9. 9, 8. 2, 11. 0, 7. 3, 6. 7, 11. 0, 10. 8, 12. 4
Determine a 95% confidence interval for the mean time for all players
