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 .

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

jupiter is mainly composed of hydrogen and helium just like a star. spectral analysis of jupiter has revealed that in addition to hydrogen and helium, the planet is made of water, methane and ammonia. those elements are in trace amounts. the core of the planet is thought to contain some rock and metallic hydrogen. i hope this will give you the answer to your question! : d

question - in 1827, john walker, a druggist in a small english town, tipped a splint with sulphur, chlorate of potash, and sulphid of antimony, and rubbed it on sandpaper, and it burst into flame. the druggist had discovered the first friction-chemical match, the kind we use to-day. it is called friction-chemical because it is made by mixing certain chemicals together and rubbing them. although walker's match did not require the bottle of acid, nevertheless it was not a good one. it could be lighted only by hard rubbing, and it sputtered and threw fire in all directions. in a few years, however, phosphorus was substituted on the tip for antimony, and the change worked wonders. the match could now be lighted with very little rubbing, and it was no longer necessary to have sandpaper upon which to rub it. it would ignite when rubbed on any dry surface, and there was no longer any sputtering. this was the phosphorus match, the match with which we are so familiar. according the paragraph what was the benefit of the new phosphorus match? it burst into flame when rubbed on sandpaper. it was made by mixing chemicals. it could be ignited on any dry surface. it threw fire in all directions.

answer - matches required natural chemicals
