4. 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
estimates that the mean number of pizzas eaten is 6.4 with a margin of error of 1.3.
Based on these values, what interval is likely to contain the true mean number of
pizzas eaten in the previous year by the population?
