Answer: The hypothesis test is left-tailed test.
The parameter tested here is population mean.
Step-by-step explanation:
Given : The null and alternative hypotheses are as follows:
[tex]H_0:\mu=6[/tex]
[tex]H_1:\mu<6[/tex]
We can see that the parameter tested here is population mean.
Also, the type of test depends on the alternative hypothesis.
Since the alternative hypothesis is left-tailed so the hypothesis test is left-tailed test.
