A test is conducted in order to find if there is a difference at the α=0.01 level of significance. In​ some randomized, double-blind clinical trials of a new vaccine, children were randomly divided into two groups. Subjects in group 1 received the new vaccine while subjects in group 2 received a control vaccine. After the first dose, 67 of 607 subjects in the experimental group (group 1) experienced fever as a side effect. After the first dose, 109 of 728 subjects in the control group​ (group 2) experienced fever as a side effect.

-What is the P-value of the test result?

-What is the test statistics?

-What is the positive value of the critical value?

-What is the upper boundary of the 99% Confidence Interval of p1-p2?

A laboratory is testing a new vaccine against virus Z. It is administered to 500 subjects (treatment group). Another 500 subjects were selected and given no vaccine (control group). After 5 months, they found that 20 subjects from the treatment group and 70 subjects from the control group were infected with the virus Z. (A) What's the probability of getting the virus if no vaccine was given? Calculate the confidence interval of the estimate. (Use 95% C.I.) (B) If the...

A research study was conducted to examine the clinical efficacy of a new antidepressant before being placed on the market. Depressed patients were randomly assigned to one of three groups: a placebo group, a group that received a low dose of the drug, and a group that received a moderate dose of the drug. After four weeks of treatment, the patients completed a depression inventory. The higher the score the more depressed the patient. The data are presented below. Placebo...
