Suppose a group of 800 smokers (who all wanted to give up smoking) were randomly assigned to receive an In a study, patients were administered either an antidepressant drug or a placebo for six weeks to evaluate if the antidepressant can help smokers quit. - Out of 324 patients who received the antidepressant, 27 were not smoking one year later.- Out of 476 patients who received the placebo, 56 were not smoking one year later.**Hypotheses:**- Null Hypothesis (\(H_0\)): \(p_{\text{drug}} - p_{\text{placebo}} = 0\)- Alternative Hypothesis (\(H_a\)): \(p_{\text{drug}} - p_{\text{placebo}} \neq 0\)**Objective:** Conduct a test to determine if the antidepressant is effective in helping smokers quit. The level of significance (\(\alpha\)) is 0.01.**Tasks:**(a) Calculate the test statistic.(b) Determine the P-value.

A person, Joe, claims to be able to "smell" an illness based on the odor of a person's clothing. Joe is given 12 shirts, each worn by a different person, some of whom had the illness and some of whom did not. The shirts were given to Joe in random order and he had to decide whether each shirt had been worn by an ill patient or by a healthy patient. joe identified 11 of the 12 shirts correctly. If we assume that Joe was just guessing, he would have probability 1/2 of correctly identifying each shirt. Find the probability that Joe would identify AT LEAST 11 shirts correctly by random guessing
