K 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=0.10. Sample statistics: d= -2.2, sd = 1.1, n = 15 Identify the null and alternative hypotheses. Choose the correct answer below. OA. Ho: Hd <0 Had 20 OC. Ho Hd So Ha Hd O ○ E. Ho: > Had so 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 OB. Ho Hd 20 Hаїна<0 OD. Ho Hd=0 Ha Hd #0 OF. Ho Hd #0 Ha d=0 the level of significance, the null hypothesis. There statistically significant evidence to reject the claim.
