Which of the following is NOT an observation about critical values? Choose the correct answer below. A. The number is a critica

Bess [88]

The correct options are;

A. The number z_α/2 is a critical value that corresponds to an area of 1 − α/2 to its left.

B. The number z_α/2 is a critical value that is a z score with the property that

it separates an area of α/2 in the right tail of the standard normal distribution.

C. A critical value is the number on the borderline separating sample statistics that are likely to occur from those that are unlikely to occur.

D. A critical value is the area in the right-tail region of the standard normal curve.

Answer:

Option D: A critical value is the area in the right - tail region of the standard normal curve.

Step-by-step explanation:

A critical value is defined as the line on a graph that makes that graph split into sections.

Now, either one or two of the sections split will fall into the “rejection region“.

So, if the test value falls into the rejection region, it means we will reject the null hypothesis.

Looking at the options given, options A, B & C are possible observations that we could deduce about critical values based on the definition given above.

Option D is not an observation because the critical value is what denotes the z-score with an area of alpha in the right tail region

Mark the points with the coordinates (4, 14), (22, 6), and (16, 18). Connect the points to form a triangle. and what type of tri

Yakvenalex [24]

Answer:

Step-by-step explanation:

You have the points (4, 14), (22, 6), and (16, 18).

It is important to remember that he first number of each point is the x-coordinate of that point and the second number of each one of them is the y-coordinate of that point.

Therefore, knowing the above, you can mark each point, as you can observe in the image attached, and then you can connect the points to form the triangle shown in the image.

Inga [223]

Answer:

subtraction property of equality

Step-by-step explanation:

The substraction property of equality is the property that states that you can solve the value of an equality by subtracting the value that is adding up to the variable by substracting it from the other side of the equality, an example would be like this:

$x+5=15\\x+5(-5)=15(-5)\\x=10$

By substracting form both sides the value that is along the "x" you get the value of the "x".
