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
First do 90-40 because together they make the right angle.
Then do 50=3x+2
48=3x
16=x
The graph shows a number line marking all numbers less that 10.
Choice a:
<span>c + 7 ≤ 3
</span><span>c ≤ 3-7
</span><span>c ≤ -4
Choice a is a wrong choice
Choice b:
</span><span>c - 3 > 1
</span><span>c > 1+3
</span><span>c > 4
Choice b is a wrong choice
Choice c:
</span><span>c - 7 < 3
</span><span>c < 3+7
</span><span>c < 10
Choice c is the correct choice</span>
