Question

deja and zhi conducted an experiment to test their hypothesis that male eggs of the american alligator only hatch at high temperatures. they conducted an experiment and their results were organized in the data table above. they concluded very high temperatures killed unhatched alligators. what comment(s) would you make to deja and zhi regarding their conclusions? alligator egg data alligator group temperature males hatched females hatched unhatched total eggs a 29℃ 84 9 7 100 b 30℃ 69 25 6 100 c 31℃ 44 48 8 100 d 32℃ 11 74 15 100 e 33℃ 2 68 30 100 a. their conclusion is supported by the data. nothing should be added or deleted. b. they should reject their hypothesis. more males hatch at low temperatures, and more females hatch at high temperatures. c. they should accept their hypothesis, and also note that more eggs fail to hatch at high temperatures. d. they did not sample very many eggs, and no pattern is apparent in the data. in order for something to be considered alive, what characteristics must it possess?

Explanation:

As temperature increases from 29°C to 33°C, the number of male - hatched alligators decreases (84, 69, 44, 11, 2) and the number of unhatched alligators increases (7, 6, 8, 15, 30). This supports the idea that high temperatures kill unhatched alligators and also shows that more males hatch at lower temperatures and more females at higher temperatures. So, their hypothesis should be rejected.

Answer:

B. They should reject their hypothesis. More males hatch at low temperatures, and more females hatch at high temperatures.
