10. A sample of the various prices for a particular product has been conducted in 16 stores which were selected at random in a neighborhood of a city. The following prices were noted: 95, 108, 97, 112, 99, 106, 105, 100, 99, 98, 104, 110, 107, 111, 103, and 110. Assuming that the prices of this product follow a normal law of variance of 25, determine the confidence interval at 95% for the population mean.
