a. Use a 0.05 significance level to test the claim that giving candy does result in greater tips. What are the null and alternative hypotheses? OA. H₂ P4-P₂ Hy: # *#₂ OC. Ho: P₁ P₂ H₁: Pg ₂ The test statistic, t, is (Round to two decimal places as needed.) The P-value is (Round to three decimal places as needed.) State the conclusion for the test. OB. H₂₂₂ H₂: Hy #₂ OD. H₂: #₁ #₂ OA. Fail to reject the null hypothesis. There is not sufficient evidence to support the claim that giving candy does result in greater tips B. Reject the null hypothesis. There is sufficient evidence to support the claim that giving candy does result in greater tips OC. Fail to reject the null hypothesis. There is sufficient evidence to support the claim that giving candy does result in greater tips. OD. Reject the null hypothesis. There is not sufficient evidence to support the claim that giving candy does result in greater tips. b. Construct the confidence interval suitable for testing the claim in part (a). <-₂0 (Round to two decimal places as needed.)
