Question

The null and alternative hypotheses are given. Determine whether the hypothesis test is​ left-tailed, right-tailed, or​ two-tailed. What parameter is being​ tested? Upper H 0H0​: muμ equals= 66 Upper H 1H1​: muμ less than< 6

Answer 1

Answer: The hypothesis test is left-tailed test.

The parameter tested here is population mean.

Explanation:

Given : The null and alternative hypotheses are as follows:

`H_0:\mu=6`

`H_1:\mu<6`

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.
