Question

4. The table be low shows chirps and temperatures for another sample of crickets. Number of Chirps (x) 28 39 42 48 52 68 78 80 93 90 A regression line was fit to predict temperature(3) based on chirps (x), resulting in the following: 38.406+1.038x a. (8 points) Use the fitted line to find the predicted temperature if there are 42 chirps. b. (5 points) If you count the chirps today and found it to be 10 higher than yesterday, how much higher do you expect the temperature to be today compared to yesterday?

Explanation / Answer

a) Expected temperature = 38.406+1.308x =38.406+1.308*42= 93.34200

b) Temperature is expected to be higher by 1.308*10=13.08 degree.
