The u. s. mint has a specification that pennies have a population mean weight of 2.5 g. assume that the weights of pennies are normally distributed and that σ = 0.0165 g. a random sample of n = 37 pennies produced in 1983 has a sample mean weight, \bar{x}= 2.499. interest centers on testing whether the population mean weight is less than 2.5 g. what is the p-value for the appropriate test?
