Is there a relationship between the number of times a cricket chirps in one minute and the temperature? To answer this, eight measurements of cricket chirps and the current temperature were collected. The linear correlation coefficient between the chirps and temperature was 0.874. The mean number of chirps was 1,016.25 and the mean temperature was 80.75. The linear regression equation for the data is Temperature = 27.63 + 0.05(Chirps), using Temperature and Chirps instead of y and x. Is there sufficient evidence of a linear correlation between the number of times a cricket chirps in one minute and the temperature? Use a 0.05 significance level and thoroughly support your answer using the table below. Find the best prediction of the temperature if a cricket chirps 900 times in a minute.
