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 answer below.
O A. Reject the null hypothesis. There is sufficient evidence to support a claim of a correlation between quality and price.
B. Fail to reject the null hypothesis. There is sufficient evidence to support a claim of a correlation between quality and price.
Reject the null hypothesis. There is insufficient evidence to support a claim of a correlation between quality and price.
D. Fail to reject the null hypothesis. There is insufficient evidence to support a claim of a correlation between quality and price.
