Answer:
B- It cannot be answered without additional information.
Step-by-step explanation:
From the question, we have α= 0.01 and α= 0.05.
Thus;
We can decide to look at the critical values and check if test statistic is less or more than the tabulated value for α= 0.01 and 0.05.
However, that will not be sufficient as neither the level of significance nor confidence level is clearly mentioned in the question and thus, we can not answer it without additional information.
Answer:
step one needs to be fixed... you are supposed to subtract 10 from both sides of the equation.
Step-by-step explanation:
STEP 1: Move all terms not containing n to the right side of the equation.

STEP 2: Divide each term by 2 and simplify.

-1 > -4
3 <u>></u> 0
1 <u>></u> -2
3 > -5
I don't understand the second one sorry.
