That is hard. I'm guessing that they still are the same shapes but they all have different lengths in certain areas that make them seem like they are the same shapes but are being seen at different angles but I can't be sure. That's why they are in the same groups although having different angles. Does it have answer choices? I will help you if it does...
Answer:
The answer is D: The inequality symbol in the alternative hypothesis points away from the critical region.
Step-by-step explanation:
We usually have a one-tailed and two-tailed tests. Examples of a one-tailed test are the left-tailed and the right tailed test. These tests are referred to as one-tailed tests because the critical region or rejection region is located in only one tail. The critical region of a left or right tailed test is that region that correlate with the rejection region and is usually located in extreme left or right tail. Furthermore, tails in a distribution are usually the extreme critical regions also known as the rejection regions which are bound by critical values. However there is nothing that suggests the statement in Option D when talking about tails in a distribution.
Yeah it is already in simplest form
From the question, we know the population standard deviation, σ = 1.63, the sample standard deviation, s = 3.07, the sample mean,

and the sample size, n = 38.
The question illustrates a hypothesis chi-square test of variance.
The test statistics for a Chi-squared test of variance is given by
Consider the given statement:

We have to identify the property used in this statement.
1. Associative Property of Addition: Let a,b and c be three real numbers. This property states that
. This property is not used in the given statement.
2. Commutative property of multiplication: Let 'a' and 'b' be two real numbers. This property states that
.
In the given statement,
This statement holds commutative property of multiplication as whether 2 is multiplied to
or
is multiplied to 2, the result is same.
So, Commutative property of multiplication is illustrated in this statement.
3. Inverse property of multiplication: A number 'a' is said to have an inverse '
' if
. This property is not used in the given statement.
4. Commutative property of addition: Let 'a' and 'b' be two real numbers. This property states that
. This property is not used in the given statement.
