A recent study showed that the average number of sticks of gum a person chews in a week is 16. The population standard deviation was 1.4. A college student believes that the guys in his dormitory chew less gum in a week. He conducts a study and samples 31 of the guys in his dorm and finds that on average they chew 14 sticks of gum in a week. Test the college student's claim at a=0.05. The correct hypotheses would be: Ο Ηo:μ < 16 HA: 16 (claim) • Η: μ > 16 HA16 (claim) Ο Η: μ = 16 HA: 16 (claim) Since the level of significance is 0.05 the critical value is -1.645 (round to 3 places) The test statistic is: The p-value is: (round to 3 places)
