Listed below are the numbers of cricket chirps in 1 minute and the corresponding temperatures in F. Construct a scatterplot, and find the value of the linear correlation coefficient r. Is there sufficient evidence to conclude that there is a linear correlation between the number of chirps in 1 minute and the temperature? Use a significance level of = 0.05. Chirps in 1 min 875 1196 1096 Temperature (F) 71.9 93.2 84.3 857 74.4 1215 89.9 1046 945 81.9 918 70.9 79.4 Construct a scatterplot. Choose the correct graph below. A. 1500- B. 1500 Temperature (F) 50 100 Chirps in 1 min Ly Chirps in 1 min 50 100 Temperature (F) Ly Chirps in 1 min 1500 50 100 Temperature (F) What are the null and alternative hypotheses? A. Ho p=0 H p>0 c. Ho p=0 Hp 0 The linear correlation coefficient r is 0.924. (Round to three decimal places as needed.) B. Ho: p=0 H p=0. D. Ho p=0 H p
