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

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:

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.

e) none of the above because the measure of angle cba is 101°

idk lol
