The sample size needs to be 96.
First we find the z-score for this confidence interval:
Convert 95% to a decimal: 95/100 = 0.95
Subtract from 1: 1 - 0.95 = 0.05
Divide by 2: 0.05/2 = 0.025
Subtract from 1: 1 = 0.025 = 0.975
Using a z-table (http://www.z-table.com) we look up this value in the chart; the z-score that goes with this value is 1.96.
Now we use the formula

Answer:
(6, 4)
Step-by-step explanation:
The midpoint is found as the average of the coordinates of the end points.
M = (A +B)/2
M = ((9, 1) +(3, 7))/2 = (9+3, 1+7)/2 = (12, 8)/2
M = (6, 4)
The midpoint of segment AB is (x, y) = (6, 4).
Aimee is correct because a stop sign is an octogon. Octogons contain only obtuse angles.
