Answer:
Power
Step-by-step explanation:
An hypothesis is usually formulated at the beginning of research, it is usually in line with the problem statement and gives the possible outcome.
An hypothesis is either accepted or rejected.
Power in hypothesis is the probability of rejecting null hypothesis when it is false. It helps in making a correct decision by rejecting the null hypothesis when it is not true.
power ranges between 0 to 1 when it is close to 1 it is said to be very strong and has the probability of rejecting a null hypothesis when it is not true.
Power helps to avoid a type II error in statistics.
D is the answer because if you calculate the answer correctly. that will be so.
3 (-3^2 × 1^5) + 4 (-3 - 8)^2
3 (9 × 1) = 27 + 4 (121) = 484
27 + 484 = 511
