A sample of 14 fish from Lake Norman gave the mean weight of x1=23 ounces with a standarddeviation of s1= 3 ounces. A sample of 16 fish from Lake Wylie gave the mean weight of x2=25ounces with a standard deviation of s2=4 ounces. Assume that the weight of fish for both lakesare normally distributed with equal population standard deviations. Test at =.01 significance level,if the mean weights of fish are different for these two lakes
