An experiment was conducted to test the effect of a new drug on a viral infection. After the infection was induced in 100 mice, the mice were randomly split into two groups of 50. The first group, the control group, received no treatment for the infection, and the second group received the drug. After a 30-day period, the proportions of survivors, p̂1 and p̂2, in the two groups were found to be 0.4 and 0.60, respectively.

Find the test statistic and rejection region. (Round your answers to two decimal places. If the test is one-tailed, enter NONE for the unused region.

z = ?? (please do not use (p1-p2) / SE as it does not work. I have tried this multiple times)

z < = -1.65

z > = NONE

(b) Use a 95% confidence interval to estimate the actual difference (p1 − p2) in the survival rates for the treated versus the control groups. (Round your answers to two decimal places.)

A researcher was conducted to test the effect of a new drug on viral infection. The infection was put on a group of mice and the mice was randomly split into two groups, different groups. The first group (control group), received no treatment for the infection. The second group received the drug. After a 30-day period, the number of survivors in the two groups were observed, and the test statistic was calculated to be z  =  1.46. If we wish...

You are testing the effect of a new drug to treat severe viral pneumonia. To do this you conduct a randomized controlled trial. You enroll 200 participants in your study; 100 are allocated to the intervention arm (they receive the drug) and 100 receive the current standard of care. 7 of the participants in the intervention arm and 15 of the participants in the standard care arm die of pneumonia. a)Calculate the RR of survival. Round to the nearest hundredth....

To test the effectiveness of a new drug (Phasomaxtrin) designed to treat Quarantinitis, researchers conducted a clinical trial. The subjects were 512 adult American volunteers with advanced Quarantinitis. Half were randomly assigned to take the drug and the other half were randomly assigned to take a placebo. Neither the subjects nor the doctors who evaluated them knew who was in which group. After three years, 32 percent of those who got Phasomaxtrin were no longer afraid to keep staying inside,...
