Weights of a certain species of snails are normally distributed with a mean, y = 81g and a standard deviation , o = 22g. Draw diagrams to help you solve the following problems. 1. What is the probability that a snail weighs more than 98g? (4 dp) 2. What proportion of snails will weigh between 67g and 98g? (4 dp) 3. If you had 250 snails of this species, how many of them would you expect to weigh between 67g and 98g? (round to nearest integer)
