A clinical trial is conducted comparing a new pain reliever for arthritis to a placebo. Participants are randomly assigned to receive the new treatment or a placebo and the outcome is pain relief within 30 minutes. The data are shown here.
| Pain Relief | No Pain Relief | |
| New Medication | 45 | 75 |
| Placebo | 20 | 100 |
Is there a significant difference in the proportions of
patients reporting pain relief?
Run the test at a 5% level of significance.
H0: p1= p2(equivalent to RD = 0, RR=1 or OR=1)
Can they reject the H0?
Group of answer choices
Yes, Reject H0, there is a statistically significant difference in the proportions of patients reporting pain relief in the new medication and placebo groups
No, Fail to Reject H0, there is no statistically significant difference in the proportions of patients reporting pain relief between the new medication and placebo groups

A clinical trial is conducted comparing a new pain reliever for arthritis to a placebo.
A clinical trial is conducted comparing a new pain reliever for arthritis to a placebo. Participants are randomly assigned to receive the new treatment or a placebo and the outcome is pain relief within 30 minutes. Of the 120 participants who received the new medication, 44 reported pain relief, while 21 out of the 120 participants who received the placebo reported pain relief. Is there a significant difference in the proportions of patients reporting pain relief? Run the test...

A study was performed comparing the efficacy of a new pain
reliever, Galproxidone, to several pain relievers commonly
prescribed after orthopedic surgury. Patients were asked to rate
their pain after taking each medication. The data is listed below.
Perform an ANOVA to determine the relative efficacy of Galproxidone
on pain relief compared to the other pain relievers. If differences
exist, perform a Bonferoni post-hoc test to determine which pain
relievers are different from Galproxidone. Interpret the final
results in terms...

A sample of 800 arthritis patients participate in a test of a
new pain reliever. 624
of the participants rate their pain as ‘substantially reduced’.
Give a 95% lower bound
confidence interval for the proportion of arthritis patients
whose pain would be
substantially reduced when taking the new pain reliever.
Interpret your result.

1. A clinical trial is conducted to compare an experimental
medication to placebo to reduce the symptoms of asthma. Two hundred
participants are enrolled in the study and randomized to receive
either the experimental medication or placebo. The primary outcome
is self-reported reduction of symptoms. Among 100 participants who
receive the experimental medication, 38 report a reduction of
symptoms as compared to 21 participants of 100 assigned to placebo.

A clinical trial is conducted comparing a new (investigational)
analgesic drug to one already on the market (Tylenol) for arthritis
pain. Participants were randomly assigned to only one of the two
treatment groups and the outcome was self-reported pain relief
within 30 minutes. The 2 x 2 crosstab analysis with SPSS produced

Two different pain reliever drugs, “Drug A” and “Drug B,” are
developed to relieve arthritis pain. A clinical study recruits 15
individuals with arthritis. The individuals are given each drug on
different days and the number of hours of pain relief for each drug
is recorded. This data is in the “arthritis.csv” data file. a)
State the appropriate hypotheses to test if there is a difference
in the hours of pain relief for Drug A versus Drug B, using “Drug...
