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.
