Answer:
a. committed a type 1 error
Step-by-step explanation:
The correct option is - a. committed a type 1 error
Reason -
Type 1 error occurs when a true null Hypothesis is rejected
Type 2 error occurs when a false null Hypothesis is accepted
Now,
Let us state that,
The null hypothesis and alternate hypothesis is
H0 : There is no difference between the mean lifetimes of the new and old designs
H1 : There is a difference between the mean lifetimes of the new and old designs
Now,
As there is no difference between the mean lifetimes of the new and old designs.
⇒ The null hypothesis is true.
But p value suggests that null hypothesis should be rejected
∴
We have committed a Type 1 error that is rejecting a true null hypothesis.
So,
The correct option is - a. committed a type 1 error
If its the division then it is 0.3
Your answer would be 4.
If we substitute in x = -8 and y = -4 into the expression, we get:
This then becomes:
= = 4.
I hope this helps!
I think it's y=-1/2x+8
Because if you use two and seven for example you could substitute the x and have:
y=-1/2(2)+8
y=-1+8
y=7
which proves the equation correct
So the answer is y=-1/2x+8
