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. Brea lives the farthest from school
Step-by-step explanation:
The easiest way to go about this is to get them all to the same unit. Let's do meters :)
3 kilometers = 3,000 meters (Kai)
30,000 centimeters = 300 meters (Cal)
and then of course 30,000 meters is already in the correct unit (Brea)
Given all of this, you can easily tell that the answer is D
