3x - 6y = -2
-6y = -3x - 2, divide through by -1
6y = 3x + 2, divide through by 6
y = 3x/6 + 2/6
y = x/2 + 1/3
The answers are
x=5
n=3
y=4
k=-80
Answer: B) type II error
Step-by-step explanation: whenever hypothesis test is performed it is not possible to be 100% certain about the conclusion or decision made, hence their must be a level of confidence for the conclusion made.
The level of significance (α) usually takes the lower percentage of the area of distribution.
When you reject the null hypothesis instead of accepting it, you commit a type I error, the probability of committing this error is the level of significance (α).
When you accept the null hypothesis when you are suppose to reject it, you commit a type II error and the probability of committing this error is confidence level (β) which is (1- α)
