Average length of trout caught in Swanson lake is u=19.For a random sample of 51 fish caught the mean length was xbar=18.5 inches with estimated standard deviation s=3.2 inches. Do these data indicate that the average length of trout caught in Swanson lake is less than u=19 inches? Use the level of significance a=0.05
