Population mean is the parameter which is tested.
Step-by-step explanation:
Given :
We know that , the alternative hypothesis () indicates kind of the hypothesis test we need to perform whether left-tailed, right-tailed, or two-tailed.
Here, the alternative hypothesis () is two-tailed, so the hypothesis test is a two-tailed test.

Step-by-step explanation:
3(2x + 4) = -6
6x + 12 = -6
6x = -6 - 12
6x = - 18
x = -18/6
x = -3
