Have a great weekend:) In a study of treatments for very painful &#34;cluster&#34; headaches, 151 patients were treated with oxygen and 156 other patients were given a placebo consisting of ordinary air.

Thereevidence to support the claim that the cure rate with oxygen treatment is higher than the cure rate for those given a placebo.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?Because the confidence interval limits0, it appears that the two cure rates areBecause the confidence interval limits includevalues, it appears that the cure rate isfor the oxygen treatmentthan for the placebo.c. Based on the results, is the oxygen treatment effective?OA. The results suggest that the oxygen treatment is not effective in curing &#34;cluster&#34; headaches because the cure rate for the oxygen treatment appears to be lower than that of the placebo.OB. The results suggest that the oxygen treatment is effective in curing &#34;cluster&#34; headaches.OC. The results suggest that the oxygen treatment is not effective in curing &#34;cluster&#34; headaches because the cure rates appear to be the sameOD. The results are inconclusive.
