Determine the null and alternative hypotheses for this test. Choose the correct answer below.
O B. Ho: Ps #0
H: Pg =0
O A. Ho: Ps =0
H: Ps #0
OC. Ho: rs =0
O D. Ho: rg #0
H:g =0
Transcribed Image Text:Find the value of the correlation coefficient.
(Round to three decimal places as needed.)
Determine the critical value(s) of the correlation coefficient.
(Round to three decimal places as needed. Use a comma to separate answers as needed.)
Choose the correct conclusion below.
A. Reject the null hypothesis. There does not appear to be a correlation between the number of chirps in 1 min and the temperature.
B. Fail to reject the null hypothesis. There appears to be a correlation
tween the number of chirps in 1 min and the temperature.
C. Fail to reject the null hypothesis. There does not appear to be a correlation between the number of chirps in 1 min and the temperature.
D. Reject the null hypothesis. There appears to be a correlation between the number of chirps in 1 min and the temperature.
