Use the following information for Questions 11-15: A town is trying to determine if a new recycling incentive would increase the number of people that separate their garbage from the recyclable items. To make this determination, a simple random sample of 10 streets are selected and the number of people that recycle on these streets is counted once before and once after the recycling incentive has been initiated. The data shows a mean difference of 4.72 and a standard deviation of 1.44. Determine if the recycling incentive was effective with a 10% significance level. Part e: Determine the conclusion. a) O Fail to Reject the Null Hypothesis b) Accept the Null Hypothesis c) Accept the Alternate Hypothesis d) Reject the Null Hypothesis e) Reject the Alternate Hypothesis Question 16 Your answer is INCORRECT. Use the following information to answer Questions 16-20: The belief is that the mean number of hours per week of part-time work of high school seniors in a city is 10.5 hours. Data from a simple random sample of 23 high school seniors indicated that their mean number of part-time work was 11.5 with a standard deviation of 1.4. Test whether these data cast doubt on the current belief. (use a = 0.05) Part a: Determine the Null and Alternate Hypotheses Ho: H = 10.5; Ha: H # 10.5 b) H H = 10.5; Ha: H 1.282 b) Ot 1.383 e) Ot 1.833 Question Your answer is CORRECT.
