Answer:
The z-statistic lies in the critical region
Step-by-step explanation:
When a hypothesis test is performed, the decision to reject or not reject the null hypothesis is made on basis of following observations:
- If the z-statistic falls in the critical or rejection region, there is enough evidence to reject the Null Hypothesis
- If the z-statistic falls outside the critical or rejection region, there is not enough evidence to reject the Null Hypothesis.
In the given statement Zachary rejects the Null Hypothesis, this means the z-statistic she calculated must have been inside the critical or rejection region. Hence the correct answer would be:
The z-statistic lies in the critical region
Answer:
Step-by-step explanation:
Here is how to get 9:
3x = 4(x - 2.25)
Solve 4(x - 2.25)
3x = 4x - 9
Move the variable to the left side and change it's sign
3x - 4x = -9
Combine like terms
-x = -9
change the signs
x = 9
There ya go! I hope this isn't too confusing!
