Decide whether to reject the null hypothesis. Choose the correct answer below. O A. Reject the null hypothesis because the P-value is greater than the significance level, c. B. Fail to reject the null hypothesis because the P-value is less than or equal to the significance level, c. O C. Fail to reject the null hypothesis because the P-value is greater than the significance level, c. O D. Reject the null hypothesis because the P-value is less than or equal to the significance level, c. e. What is the final conclusion? O A. There is not sufficient evidence to support the claim that less than 9% of treated subjects experienced headaches. B. There is not sufficient evidence to warrant rejection of the claim that less than 9% of treated subjects experienced headaches. O C. There is sufficient evidence to support the claim that less than 9% of treated subjects experienced headaches. D. There is sufficient evidence to warrant rejection of the claim that less than 9% of treated subjects experienced headaches.
