Answer: Two-tailed test.

Population mean is the parameter which is tested.

Explanation:

Given :
H_0: \mu=105


H_1:\mu\\eq105

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

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

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

Thus , Population mean is the parameter which is tested.
