A coin-operated drink machine was designed to discharge a mean of ounces of coffee per cup. In a test of the machine, the discharge amounts in randomly chosen cups of coffee from the machine were recorded. The sample mean and sample standard deviation were ounces and ounces, respectively. If we assume that the discharge amounts are normally distributed, is there enough evidence, at the level of significance, to conclude that the true mean discharge, , differs from ounces?Perform a two-tailed test.
Find the null hypothesis, the alternative hypothesis, the type of test statistic, the value of the test statistic, and the p-value
