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 α = 0.05. Chirps in 1 min 881 Temperature (°F) 71 1195 1098 854 92 85.3 75.8 1205 1035 958 905 lo 88.5 70.2 79.5 81.6 Construct a scatterplot. Choose the correct graph below. O A. OB. O D.

What are the null and alternative hypotheses? A. Ho: p=0 'B. Ho:p=0 H₁: p<0 H₁: p=0 O C. Ho:p#0 D. Ho: p=0 H₁: p>0 H₁: p=0 The linear correlation coefficient r is 0.843. (Round to three decimal places as needed.) The test statistic t is 3.83. (Round to two decimal places as needed.) The P-value is 0.009. (Round to three decimal places as needed.) is sufficient evidence to support the claim that there is a linear correlation between the Because the P-value is less than or equal to the significance level 0.05, reject the null hypothesis. There number of chirps in 1 minute and the temperature in °F for a significance level of a = 0.05.
