Scientists have linked a catastrophic decline in the number of frogs inhabiting the world to ultraviolet radiation from the earth’s depleted ozone layer. The Pacific tree frog, however, is not believed to be in decline because it produces an enzyme that appears to protect its eggs from ultraviolet radiation. Read the following abstract and answer the following question. Methods: … compared the hatching rates of two groups of Pacific tree frog eggs. One group of eggs was shielded with ultraviolet-blocking sun shades, whereas the second group was not. The number of eggs successfully hatched in each group was recorded. Results: A total of 34 of the 70 eggs shielded by sun shades hatched, while 31 of 80 eggs not shielded hatched. The p -value for comparing the hatching rates between the two groups is p -value = 0.224. What does the p-value show
