Answer:
B.
Step-by-step explanation:
Point estimate is always at the center of the interval.
You can find it by averaging the endpoints:
p(hat) = (0.028 + 0.086)/2 = 0.057
X is 90 degrees. If AB is the diameter, then it passes through the centre. X is 90 degrees because the angle in a semicircle is always a right angle.
