Answer:
A
Step-by-step explanation:
Basically, this is an observational study because the researcher does not apply any treatment.
It's not an experiment because there is no experimentation involved. :)
It's not double-blind because in that case the researcher would have to apply something to two kinds of groups. one aware one the other not. not the case.
It's not D because The observations are comparing two kinds of subjects and they are not looking for a cause and effect.
That's 4! (faculty), ie., 4x3x2x1 = 24.
one of four can win, then there are 3 left for second place, and so on...
<h3>Annual percent growth is 4.37 %</h3>
<em><u>Solution:</u></em>
<em><u>The increasing function is given as:</u></em>

Where,
y is future value
a is initial value
r is growth rate
t is number of years
From given,
a = 5000
y = 9500
t = 1997 to 2012 = 15 years
r = ?
<em><u>Substituting the values we get,</u></em>

Thus annual percent growth is 4.37 %
Since it decreased by 5 do 5 divided by 30 and you get the answer to be 16%
