2. The amount of pyridoxine (in grams) in a multiple vitamin is normally distributed with  μ   = 110 grams and   σ  = 25 grams. What is the probability that a randomly selected vitamin will contain between 82 and 100 grams of pyridoxine?   3. The owner of a fish market determined that the average weight for a catfish is 3.2 pounds with a standard deviation of 0.8 pound. Assuming the weights of catfish are normally distributed, above what weight (in pounds) do 89.80% of the weights occur? 4. The amount of pyridoxine (in grams) in a multiple vitamin is normally distributed with  μ   = 110 grams and   σ  = 25 grams. What is the probability that a randomly selected vitamin will contain less than 100 grams and more than 120 grams of pyridoxine?
