P= 0.998 (Round to three decimal places as needed.) Decide whether to reject or fail to reject the null hypothesis. Choose the correct answer below. O A. Fail to reject Ho. At the 10% level of significance, there is enough evidence to reject the claim. O B. Reject Ho. At the 10% level of significance, there is enough evidence to reject the claim. OC. Fail to reject Ho. At the 10% level of significance, there is not enough evidence to reject the claim. O D. Reject Ho. At the 10% level of significance, there is not enough evidence to reject the claim.
