Identify the test statistic. (Round to two decimal places as needed.) Identify the P-value. P-value= (Round to three decimal places as needed.) What is the conclusion based on the hypothesis test? The P-value is the significance level of a=0.01, so b. Test the claim by constructing an appropriate confidence interval. The 98% confidence interval is < (P₁-P₂)< (Round to three decimal places as needed.) What is the conclusion based on the confidence interval? the null hypothesis. There evidence to support the claim that the cure rate with oxygen treatment is higher than the cure rate for those given a placebo. Because the confidence interval limits c. Based on the results, is the oxygen treatment effective? OA. The results suggest that the oxygen treatment is effective in curing "cluster" headaches. OB. The results suggest that the oxygen treatment is not effective in curing "cluster" headaches because the cure rate for the oxygen treatment appears to be lower than that of the placebo. OC. The results suggest that the oxygen treatment is not effective in curing "cluster" headaches because the cure rates appear to be the same. 0, it appears that the two cure rates are Because the confidence interval limits include values, it appears that the cure rate is for the oxygen treatment than for the placebo.
