The label on the bottles of spring water of a certain brand says 250 milliliters. A random sample of 20 bottles has an average of 248 milliliters. Suppose we know that the population, which is normally distributed, has a standard deviation of 2.5 milliliters. Does this seem to indicate that the population mean volume of a bottle is 250 milliliters?
