The island of Yapoah grows two types of potatoes: red and purple. You wonder if the purple potatoes are larger, on average, than the red potatoes. You collect a random sample of 52 purple potatoes and find an average volume (in cubic millimeters) of 115 together with a standard deviation of 23. You also collect a random sample of 45 red potatoes and find an average volume of 108 with a standard deviation of 30.
