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

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.

Q2. A certain anti-viral drug is used to cure an infection and
the recovery time being
normally distributed with a mean of 28.2 months and standard
deviation of 4.2 months. 25
patients who were administered this drug were randomly selected.
Now, answer the
following questions with necessary justification.
(Be careful to always first check if conditions are appropriate to
answer each question.
Otherwise, do not proceed with calculation.) [2+2+2+2+2+3=13

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,...
