A recent study showed that the average number of sticks of gum a person chews in a week is 10. The population standard deviation was 2.3. A college student believes that the guys in his dormitory chew a different amount of gum in a week. He conducts a study and samples 45 of the guys in his dorm and finds that on average they chew 11 sticks of gum in a week. Test the college student's claim at αα=0.01.
Since the level of significance is 0.01 the critical value is 2.576 and -2.576

The test statistic is: (round to 3 places)

The p-value is: (round to 3 places)
