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
Standard Equation for trig function: y = A cos (B (x - H))+ K
*Here, we are just dealing with A (amplitude) and B (period)
Period = 2π/ b
8 = 2π/ b
Solve for b: 2π/8 or π/4
Equation: y = 2 cos (π/4 (x))
