Unformatted text preview: Math 300 – Quiz for Chapter 8 Printed Name: Calculators are allowed on this quiz...neighbors are not !
1 A recent study stated that if a person chewed gum, the average number of sticks of gum he or she chewed
daily was 8. To test the claim, a researcher selected a random sample of 36 gum chewers and found the mean
number of sticks of gum chewed per day was 9. The standard deviation of the population is 1. At α = 0.05,
is the number of sticks of gum a person chews per day actually greater than 8?
