In a survey of 64 random studentsI 39 indicated that they preferred outdoor exercise over exercising in a gym. The 9596 condence interval estimating the proportion of all students at the university who prefer outdoor exercise is given by which of the following? Question ll options: 51W 51W Question 12 (1 point} Sa vea' In the year 2000, the average car had a fuel economy of 22.? MPG. You are curious as to whether the average in the present day is greater than the historical value. What are the appropriate hypotheses for this test? Question 12 options: Question 13 (1 point) Saved A medical researcher wants to determine if the average hospital stay after a certain procedure is different from 14.37 days. The hypotheses for this scenario are as follows: Null Hypothesis: H = 14.37, Alternative Hypothesis: ( # 14.37. If the researcher randomly samples 26 patients that underwent the procedure and determines their average hospital stay was 13.16 days with a standard deviation of 5.19 days, what is the test statistic and p- value of this test? Question 13 options: 12 Test Statistic: -1.189. P-Value: 0 8772 21 Test Statistic: -1.189. P-Value: 0.12285 31 Test Statistic: -1.189, P-Value: 18772 41 Test Statistic: -1.189. P-Value: 0.2457 5 Test Statistic: 1.189. P-Value: 0.2457 Question 14 (1 point) You are interested in whether the average lifetime of Duracell AAA batteries is different from the average lifetime of Energizer AAA batteries. You lay out your hypotheses as follows: Null Hypothesis: U1_= H2, Alternative Hypothesis: U1 # 12. After running a two independent samples t-test, you see a p-value of 0.2941. What is the appropriate conclusion? Question 14 options: 1) The average lifetime of Duracell AAA batteries is equal to the average lifetime of Energizer AAA batteries. 2) We did not find enough evidence to say the average lifetime of Duracell AAA batteries is less than th average lifetime of Energizer AAA batteries. We did not find enough evidence to say the average lifetime of Duracell AAA batteries is greater than the average lifetime of Energizer AAA batteries. We did not find enough evidence to say a significant difference exists between the average lifetime of Duracell AAA batteries and the average lifetime of Energizer AAA batteries 5) The average lifetime of Duracell AAA batteries is significantly different from the average lifetime of Energizer AAA batteries
