A pizza company is interested in the average number of pizzas eaten each year by people. They send out 30 volunteers to conduct research by collecting random samples of 25 people each and determine the number of pizzas that the people in the group ate in the previous year. After looking at the sample means, the company sees that the distribution is approximately normal, with a mean of 6.4 pizzas eaten and a standard deviation of 0.6 pizzas. Label the normal curve to show 3 standard deviations from the mean.
