Answer:
f(3) = 26
Step-by-step explanation:
Average rate of change of a function on an interval is;
f(a) - f(b)/(a-b)
Here, we want to find the value of f(-3)
To find the average rate of change on the given interval;
we have;
f(3) - f(-2)/3-(-2) = 17/5
f(3)-9/5 = 17/5
Since denominator is same, we equate numerator;
f(3)-9 = 17
f(3) = 17 + 9
f(3) = 26

Answer:
difference in the proportion = 0.0452
Step-by-step explanation:
x1 = 27, n1 = 193,
p1 = 27/193
p1 = 0.1399
x2 = 16, n2 = 169,
p2 = 16/169
p2 = 0.0947
a) The best estimate for the difference in the proportion of smokers, using male proportion minus female proportion is 0.0452. Male smokes more than females in given sample.
p1 - p2 = 0.1399 - 0.0947
p1 - p2 = 0.0452
