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:
a = ![\sqrt{7}](https://tex.z-dn.net/?f=%5Csqrt%7B7%7D)
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.:
<em>Suppose ABC is a right triangle with sides a, b, and c and right angle at C. Find the unknown side length using the Pythagorean theorem and then find the values of the six trigonometric functions for angle B. when b=3 and c=4</em>.
My answer:
We will Pythagoras theorem, which states that the sum of squares of two legs of a right triangle is equal to the square of the hypotenuse of right triangle. Because the question says that ABC is a right triangle.
![a^2+b^2=c^2](https://tex.z-dn.net/?f=a%5E2%2Bb%5E2%3Dc%5E2)
Given that: b=3 and c=4
![a^2+3^2=4^2a^2+9=16a^2+9-9=16-9a^2=7](https://tex.z-dn.net/?f=a%5E2%2B3%5E2%3D4%5E2a%5E2%2B9%3D16a%5E2%2B9-9%3D16-9a%5E2%3D7)
so a =
We know that tangent relates opposite side of a right triangle with adjacent side.
![\text{tan}(B)=\frac{a}{b}\\\text{tan}(B)=\frac{\sqrt{7}}{3}](https://tex.z-dn.net/?f=%5Ctext%7Btan%7D%28B%29%3D%5Cfrac%7Ba%7D%7Bb%7D%5C%5C%5Ctext%7Btan%7D%28B%29%3D%5Cfrac%7B%5Csqrt%7B7%7D%7D%7B3%7D)
