Question

A new drug has been developed to treat a particular condition, and it is alleged to be more effective than traditional treatment. An experiment will be conducted to test whether the claim is true. To perform the hypothesis test, a 99% confidence level is selected for the hypothesis test. The new drug will be administered to a sample of 200 individuals with the condition, selected at random. Another 300 individuals are randomly selected to receive the traditional treatment. Of the 200 individuals treated with the new drug, 140 were completely cured. Of those treated with the traditional method, 180 were completely cured. to.

Is there statistical evidence to support the claim that the new drug is more effective? Take the proper test and finish (10 pts)

b. If you were a patient of this condition, which treatment would you select? Justify your answer (7 pts)

A drug company has developed a new drug designed to prevent
colds. They state that the drug is effective for both men and
women. In a sample of 150 men, 68 caught a cold. In a sample of 200
women, 60 caught a cold. At á = 0.05, test the claim that there is
no difference in the proportion of men and women who caught a
cold.

A new type of medication has been developed for the treatment of
a certain type
of disease. It is known that; the standard deviation for the
average recovery times of patients
treated with this medication is , σ = 2 . Randomly selected 12
patients were treated with this
medication and the recovery days are given as;
Xi: 12, 5, 8, 12, 6, 6, 12, 17, 18, 5, 12, 13 i = 1, … , n

A new beta-blocker medication is being tested to treat high
blood pressure. Subjects with high blood pressure volunteered to
take part in the experiment. 160 subjects were randomly assigned to
receive a placebo and 210 received the medicine. High blood
pressure disappeared in 100 of the controls and in 112 of the
treatment group. Test the claim that the new beta-blocker medicine
is effective at a significance level of αα = 0.05.
What are the correct hypotheses?
