Assume that a sample is used to estimate a population proportion p. Find the margin of error M.E. that corresponds to a sample of size 177 with 25 successes at a confidence level of 80%.
M.E. -
(report answer accurate to one decimal place; answer should be reported as a percent, not a decimal-
though do not type the percent sign)
Answer should be obtained without any preliminary rounding. However, the critical value may be rounded
to 3 decimal places.

ANSWER

(-∞,-1)U(-1,2)U(2,∞)

EXPLANATION

The given functions are;

$f(x) = {(x + 1)}^{ - 1}$

and

g(x)=(x-2)

$f(x) \div g(x) = {(x + 1)}^{ - 1} \div (x - 2)$

$f(x) \div g(x) = \frac{1}{x + 1} \div (x - 2)$

$f(x) \div g(x) = \frac{1}{(x + 1)(x - 2)}$

The domain is

(-∞,-1)U(-1,2)U(2,∞)
