Question

The experimenter conducts the statistical analyses and finds that participants in the experimental condition (i.e., those who consumed 3 alcoholic beverages) reported more positive emotions than did participants in the neutral condition (i.e., those consumed 3 non-alcoholic beverages). Importantly, this observed difference in emotional responses surpassed the threshold for significance (p <.05).
1. Given this evidence, the researcher should accept the null hypothesis. A. True • B. False C. Not enough information .
2. Given this evidence, the researcher should reject the null hypothesis. A. True B. False C. Not enough information .
3. Given this evidence, the researcher should accept the alternative hypothesis. A. True B. False C. Not enough information . . .
4. Given this evidence, the researchers should reject the alternative hypothesis. A. True B. False C. Not enough information .

Answer 1

Answer:

1. False

2.True

3.True

4.false

Explanation:

Given that the difference surpasses the threshold level it means the experiment is highly significant according to statistics a p-value less than 0.05 (p ≤ 0.05) is statistically significant.

This shows that the null hypothesis is less than a 5% probability correct and the alternative is more than 95% correct.

Therefore, we reject the null hypothesis, and accept the alternative hypothesis as the correct hypothesis
