Question

question 3 of 4 > refer to the bar graph showing results from the laboratory experiment comparing the resistance to bleaching at high temperatures by cool - pool corals versus warm - pool corals. in this experiment, researchers ran a statistical test to determine the significance of the results. the test gave a p value of 0.001%. suppose, however, that the test had given a p value of 50% instead. how would such a result have affected the conclusions that were drawn? the investigators would not be able to reject the null hypothesis and would conclude that cool - pool and warm - pool corals definitely had the same reaction to high temperatures. the investigators would have rejected the null hypothesis and concluded that cool - pool and warm - pool corals had

Explanation:

In statistical hypothesis - testing, a p - value of 50% (or 0.5) is much larger than the typical significance levels (e.g., 0.05 or 0.01). When the p - value is large, we fail to reject the null hypothesis. The null hypothesis in this case is likely that there is no difference in the reaction of cool - pool and warm - pool corals to high temperatures.

Answer:

The investigators would not be able to reject the null hypothesis and would conclude that cool - pool and warm - pool corals definitely had the same reaction to high temperatures.
