Suppose the weights of fish caught from pier 1 and pier 2 are normally distributed with equal population standard deviations. The natural assumption is that the mean weights of fish caught at the two piers are equal. The owner of pier 1 thinks that the average at his pier is greater. To test at the 5% level of significance that the average weights of the fish in pier 1 is more than pier 2 the null and the alternative hypotheses are
