Answer: Two-tailed test.

Population mean is the parameter which is tested.

Step-by-step explanation:

Given : [tex]H_0: \mu=105[/tex]

[tex]H_1:\mu\neq105[/tex]

We know that , the alternative hypothesis ([tex]H_1[/tex]) indicates kind of the hypothesis test we need to perform whether left-tailed, right-tailed, or two-tailed.

Here, the alternative hypothesis ([tex]H_1[/tex]) is two-tailed, so the hypothesis test is a two-tailed test.

Also, the parameter present in the hypothesis is [tex]\mu[/tex] which is a symbol to represent the population mean.

Thus , Population mean is the parameter which is tested.
