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: muîľ == 33 upper h 1h1: muîľ less than< 33 what type of test is being conducted in this problem?

We are given:

Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed.

Since the alternative hypothesis has less than sign, therefore the given hypothesis is left-tailed

What parameter is being tested?

The parameter used is , which denotes the population mean.

Please note:

The type is test determined based on the alternative hypothesis.

If the alternative hypothesis has sign, it means the hypothesis test is two-tailed

If the alternative hypothesis has sign, it means the hypothesis test is right-tailed

If the alternative hypothesis has sign, it means the hypothesis test is left-tailed
