Hi, I need help with this question. I don't understand how the test statistic and P-value.

Dropbox options: The P-value is (greater than, less than) the significance level of a=0.01, so

(fail to reject, reject) the null hypothesis. There (is not sufficient, is sufficient) evidence to support the claim that the cure rate with oxygen treatment is higher than the cure rate for those given a placebo.

Part B. I need help with confidence interval.

Dropbox options: Because the confidence interval limits (include, do not include) 0, it appears that the two cure rates are (not equal, equal). Because the confidence interval limits include (only positive, only negative, positive and negative) values, it appears that the cure rate is (lower, higher, the same) for the oxygen treatment than for the placebo.

The P-value is the significance level of a = 0.01, so 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. b. Test the claim by constructing an appropriate confidence interval. is sufficient The 98% confidence interval is P2 H1 : P1 # P2 Identify the test statistic. z= (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
