36 ÷ 4 -3(-25 +15)
-25 +15 = -10
You now have:
36 ÷ 4 -3(-10)
36 ÷ 4 = 9
Therefore, we now have:
9 -3(-10)
= 9 + 30
=39

Option c

Step-by-step explanation:

--The large-sample confidence interval

formula for proportions is valid if np ≥ 15 and n(1-p) ≥ 15. The large sample confidence

interval only contain the true value a certain percentage of the time. A 95% CI will contain the

value 95% of the time. You add 2 successes and 2 failures.
