Suppose that a farmer claims that the weights of his tomatoes are approximately Normally distributed with a mean of 100 grams and a standard deviation of 10 grams. To test this claim, you take a random sample of 50 tomatoes and classify them into 4 categories: 0–90 grams, 90–100 grams, 100–110 grams, and 110+ grams. How many tomatoes should you expect in the 90–100 gram category, assuming that the farmer’s claim is true
