Question
Determine the null and alternative hypotheses for this test. Choose the correct answer below.
YA. Ho: Ps 0
H: Ps #0
O B. Ho Ps #0
H1:Ps = 0
O D. Ho: r #0
OC. Ho: rs=0
Find the value of the correlation coefficient.
r. = 0.391 (Round to three decimal places as needed.)
Ts
Determine the critical value(s) of the correlation coefficient.
0.700,-0.700
(Round to three decimal places as needed. Use a comma to separate answers as needed.)
Choose the correct conclusion below.
O A. Reject the null hypothesis. There appears to be a correlation between the number of audience impressions and number of albums sold.
O B. Fail to reject the null hypothesis. There appears to be a correlation between the number of audience impressions and number of albums sold.
O C. Fail to reject the null hypothesis. There does not appear to be a correlation between the number of audience impressions and number of albums sold.
O D. Reject the null hypothesis. There does not appear to be a correlation between the number of audience impressions and number of albums sold.
