Spertus et al. performaed a randomized single blind study for subjects with stable coronary artery disease. They randomized subjects into two treatments groups. The first group had current angina medications optimized and the second group was tapered off existing medications and then started on long-acting diltiazem at 180mg/day. The researchers performed several tests to determine if there were significant differences in the two treatment groups at baseline. One of the characteristics of interest was the difference in the percentages of subjects who had reported a history of congestive heart failure. In the group where current medications were optimized, 16 of 49 subjects reported a history of congestive heart failure. The subjects placed on the diltiazem, 12 of the 51 subjects reported a history of congestive heart failure. What is the hypothesis and the conclusion?

In a comparative double-blind randomized study of single dose
fosfomycin trometamol with trimethoprim in the
treatment of uncomplicated urinary infections, 20 of 26 were cured
with fosfomycin trometamol and 22 of 41 were cured with
the reference drug trimethoprim.
Denote the eradication rates for fosfomycin trometamol
and the reference drug trimethoprim by p1p1 and p2p2
respectively.

Triglycerides are blood constituents that are thought to
play a role in coronary artery disease. An experiment was conducted
to
see if regular exercise could reduce
triglyceride levels. Researchers measured the concentration
of triglycerides in the blood serum
of seven male volunteers before and after participation in
a 10-week exercise program. The results are shown below. Using the
most
appropriate statistical test, does the study show that
exercise significantly reduces triglyceride levels?
