Sample size, n = 75
Point estimate, p = 52/75 = 0.693
Z at 99.7% confidence interval ≈ 2.96
Population mean interval = p+/- Z*Sqrt [p(1-p)/n]
Substituting;
Population mean interval = 0.693 +/- 2.96*Sqrt [0.693(1-0.693)/75] = 0.693+/-0.158 = (0.535,0.851) or (53.5%,85.1%)
Answer: D. a heuristic.
Step-by-step explanation: Heuristic is the use of simple mental shortcuts to solve problems and make decisions quickly and efficiently without spending a lot of time thinking about the problem and how to solve it.
