A study reports a mortality rate of 25% in patients randomised to receive drug A compared to 50% of patients randomised to receive drug B. Which of the following statements is correct?Question 8Select one:a.None of the options are correctb.The risk of mortality is reduced by 25% in patients receiving drug A compared to drug Bc.Patients randomised to receive drug A are two times more likely to die compared to those receiving drug Bd.The relative risk of mortality in patients receiving drug B is 50%e.The relative risk of mortality in patients receiving drug A compared to drug B is 0.50

Clinical decisions are influenced by:Question 1Answera.Only the patient's health beliefsb.Only the doctor's expertisec.Both the patient's and the doctor's beliefsd.Random chance

In a clinical trial I, a Drug X was tested with placebo and it was found to be better than the placebo with a p< 0.05. In clinical trial II, a Drug Y was tested with placebo and it was found to be better than the placebo with a p < 0.01. Which of the following statement is correct: Drug Y is better than drug X We can say with more confidence that drug Y is better than the placebo Drug X is effective 95% of the time and Drug Y is effective 99% of the time Drug X fails in the treatment 5% of the time

In a medical experiment, scientist want to test if the new drug is more effective than the old one. They choose two group of patients randomly. There are 33 persons in the first group for new medicine, with the mean of 5.74, standard deviation of 6.74, and 25 people in the second group for the old one with the mean of 2.77, standard deviation of 6.28. At the 5% level of significance calculate the statistical value. 1 represent the new medicine group, and 2 represent the group that takes the old one. Assume that two populations are normally distributed and their variences are euqal. (Round your answer to two decimal places)
