Test the claim below about the mean of the differences for a population of paired data at the level of significance a. Assume the samples are random and dependent, and the populations are normally distributed. Claim: 20; a=0.01. Sample statistics: d= -2.1, sd 1.1, n = 14 Identify the null and alternative hypotheses. Choose the correct answer below. OA. Ho Hd>0 Ha Ha so OC. Ho: d=0 . Ha Hd #0 OE. Ho Hd 20 Had <0 The test statistic is t= (Round to two decimal places as needed.) The P-value is (Round to three decimal places as needed.) Since the P-value is O B. Hoi Hyo Ha Hd 20 OD. Ho Hd So Ha Hd O OF. Ho Hd #0 Ha-d=0 the level of significance, the null hypothesis. There statistically significant evidence to reject the claim.
