A researcher measures the reaction time (in units of seconds) of 1010 participants in a cognitive test. The sample mean reaction time is 0.820.82 seconds with a sample standard deviation of 0.130.13 seconds. Assuming that reaction times are normally distributed, construct a 99%99\% confidence interval for the population mean reaction time.
