You are interested in whether the average lifetime of Duracell AAA batteries is less than the average lifetime of Energizer AAA batteries. You lay out your hypotheses as follows: Null Hypothesis: μ1 ≥ μ2, Alternative Hypothesis: μ1 < μ2. After running a two independent samples t-test, you see a p-value of 0.0336. What is the appropriate conclusion? Question 15 options: 1) We did not find enough evidence to say the average lifetime of Duracell AAA batteries is less than the average lifetime of Energizer AAA batteries. 2) The average lifetime of Duracell AAA batteries is significantly less than the average lifetime of Energizer AAA batteries. 3) The average lifetime of Duracell AAA batteries is significantly greater than the average lifetime of Energizer AAA batteries. 4) The average lifetime of Duracell AAA batteries is greater than or equal to 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.
