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?

Respuesta :

Answer:

We are given:

[tex]H_{0}: \mu = 33[/tex]

[tex]H_{1}: \mu < 33[/tex]

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 [tex]\mu[/tex], which denotes the population mean.

Please note:

The type is test determined based on the alternative hypothesis.

If the alternative hypothesis has [tex]\neq[/tex] sign, it means the hypothesis test is two-tailed

If the alternative hypothesis has [tex]>[/tex] sign, it means the hypothesis test is right-tailed

If the alternative hypothesis has [tex]<[/tex] sign, it means the hypothesis test is left-tailed
