A recent study showed that the average number of sticks of gum a person chews in a week is 10. A college student believes that the guys in his dormitory chew more gum in a week. He conducts a study and samples 10 of the guys in his dorm and finds that on average they chew 11 sticks of gum in a week with a standard deviation of 3.7. Test the college student's claim at a=0.10. The correct hypotheses would be: Ο H0:μ< 10 HA:H > 10 (claim) Ο H:μ Σ 10 HA:H < 10 (claim) %3D HA:H + 10 (claim) Since the level of significance is 0.10 the critical value is 1.383 The test statistic is: (round to 3 places) The p-value is: (round to 3 places) The decision can be made to: O reject Ho O do not reject Ho The final conclusion is that: O There is enough evidence to reject the claim that more gum in a week. O There is not enough evidence to reject the claim that more gum in a week. O There is enough evidence to support the claim that more gum in a week. O There is not enough evidence to support the claim that more gum in a week.
