During a routine check of the fluoride content of Gotham City's water supply, the given results were obtained from replicate analyses of a single sample: 0.511 mg/L , 0.485 mg/L , 0.509 mg/L , 0.491 mg/L , and 0.521 mg/L . Determine the mean and 90% confidence interval for the average fluoride concentration in this sample.

Mean = 0.503

Confidence interval = 0.513, 0.493
