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 a = 0.05. Chirps in 1 min 885 1175 1091 848 1192 1037 957 903 Temperature ( F) 69.8 91.2 85.3 74.5 88.2 82.2 71.7 79.7 Construct a scatterplot. Choose the correct graph below. O A. O B. O C. OD. 1500- 1500- 1500- 1500- Chirps in 1 min Temperature (F) Chirps in 1 min Temperature (OF) OHHH OHHHHHHHHHH OHHH 50 100 50 100 50 100 50 100 Chirps in 1 min Temperature (F) Chirps in 1 min Temperature ( F) What are the null and alternative hypotheses? O A. Ho: P#0 OB. Ho: P =0 H1: p =0 Hipo Hy: p# 0 The linear correlation coefficient r is. (Round to three decimal places as needed.) The test statistic t is. (Round to two decimal places as needed.) The P-value is. (Round to three decimal places as needed.) Because the P-value is the significance level 0.05, the null hypothesis. There sufficient evidence to support the claim that there is a linear correlation between the number of chirps in 1 minute and the temperature in F for a significance level of a = 0.05
