Question

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: 1 2, Alternative Hypothesis: 1 < 2. After running a two independent samples t-test, you see a p-value of 0.6389. What is the appropriate conclusion?

1) The average lifetime of Duracell AAA batteries is greater than or equal to 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) 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.

4) 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) 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.

Explanation / Answer

Here , Pvalue is greater than alpha 0.05 . We fail to reject the null hypothesis.
