The we should use ANOVA instead of several t-tests to evaluate the differences in the mean of three or more groups.
<h3>What is t test?</h3>
A t- test is a measurable test that is utilized to look at the method for two gatherings. It is many times utilized in speculation testing to decide if a cycle or treatment really meaningfully affects the number of inhabitants in interest, or whether two gatherings are not quite the same as each other.
<h3>Explain ANOVA test:</h3>
The ANOVA test permits an examination of multiple gatherings simultaneously to decide if a relationship exists between them.
<h3 /><h3>According to question:</h3>
We ought to utilize ANOVA rather than a few t-tests to assess the distinctions in the mean of at least three gatherings on the grounds that without fail, we direct a t-test (between two gatherings) there is some opportunity that a Kind I blunder is being made while doing the test.

Answer: c
Step-by-step explanation:
Because both are slopes its confusing but its c bc its in the even quadrant
The midpoint is the average of the endpoint coords.
If (x,y) is F, then -6=(-14+x)/2 and 7=(13+y)/2.
<span>-14+x=-12 so x=2, and 14=13+y, so y=1 and F is (2,1).</span>
Y intercept is (0, -32)
x intercept is (3.2, 0) or (16/5, 0)
<3
The answer is:
(Option 1).
(Option 4).
(Option 5).
The explanation for this answer is shown below:
1. The commutative property of addtion establishes that if you change the order of the addends, the sum will not change.
2. Let's say that
and
are real numbers, Then they can added them to obtain a result
:

3. If you change the order, you will obtain the same result:

4. Therefore, the only options that show the applicaction of this property, are the options shown above.
