Answer:
Two-tailed test.
Step-by-step explanation:
There are two types of tests:
One-tailed tests and two-tailed tests.
When we only test if the mean is less or more than a value, we have a one-tailed test.
When we test if the mean is different from a value, we have a two-tailed test.
If you were to conduct a test to determine whether there is evidence that the proportion is different from 0.30, which test would you use?
Test if it is different, so a two-tailed test.
Answer:
(x-10)(x-2)
Formula:
a^{2} - b^{2} = (a-b)(a+b)
Explanation:
(x-6)^2-4^2
Then we can simplify to, (x-6-4)(x-6+4)
Which comes to your answer, (x-10)(x-2)
