2.4. A biologist reported the following set of observations While sitting on my porch during the afternoon and early evening, I could not help but notice the chirping of the crickets. I noticed that the rate of their chirping slowly diminished as the sun approached the horizon I wondered why this should be so. At first I guessed that it was due to the loss of light as the sun disappeared and night came on Accordingly, I counted the number of chirps given by ten individual crickets in the laboratory as they were exposed to less and less light intensity The following data were obtained At 10 candlepower: 48 chirps per minute At 8 candlepower 46 chirps per minute At 6 candlepower: 49 chirps per minutes At 4 candlepower: 55 chirps per minute At 2 candlepower: 47 chirps per minute At 0 candlepower:48 chirps per minute a. Formulate the hypothesis being tested in a deductive syllogism (if...then format) b. Do the results confirm or reject the second hypothesis? Explain your answer. The biologist continued: I then wondered if temperature might be affecting the number of chirps. I reasoned that, as the sun set, the temperature would drop as night approached. Accordingly, in the laboratory I kept theExplanation / Answer
Answer 2.4. A) Formulated hypothesis (In a deductive Syllogism); As the intensity of sunlight gets diminished during the night as compared to the day, the chirping of crickets must become lower in the response of low-intensity artificial light similar to the sunlight response.
B) The result of this experiment Reject the hypothesis; because chirps obtained per minute are almost equal for different numbers of candlepower such that 48 chirps per minute in 10 candlepower and also in 0 candlepower. it means that the hypothesis is rejected as per the obtained data.
C) Hypothesis: As the temperature drops at night, the chirping of crickets must be decreased in response to low temperature at night.
D) The result obtained from the experiment confirms the hypothesis because a number of chirps per minute are highest as 55 at 34*C and decrease as the temperature drops down. it means that the number of chirps is decreased as the temperature drops at night. hence, confirming the hypothesis.
