When measuring the length of the bluefin tuna, that is the legal size to harvest. The minimum length is 73 inches, and the maximum is 95 inches. Using this example, explain the normal curve with items such as the mean and standard deviation. What do the areas in the intervals - to + , - 2 to + 2, and - 3 to + 3 represent concerning areas under the normal curve? With the mean and standard deviation, calculate what the actual intervals are for your normal curve.
