Answer:
D
Step-by-step explanation:
You would get .40 as the answer and do 3 times .40 to get 1.20 as the answer.
Mean = 3550
SD = 870
Find P(1810 <x<4420)
z = x -mean / sd
= (1810 - 3550 / 870) < z< (4420 - 3550 / 870)
= -2 <z< 1
Using the -z table -2 = 0.0228 and 1 = 0.8413
Subtract: 0.8413 - 0.0228 = 0.8185 x 100 = 81.85%
Rounding everything may change answer slightly so
The closest one is B 81.5%
