Answer #1

solution:

the null hypothesis is tested vs alternative hypothesis.

and there are three types of test

left tailed test : in which alternative hypothesis contain the less than sign

right tailed test: in which alternative hypothesis contain the right than (>) sign.

two tailed test: in which alternative hypothesis contain the not equal to ( ) sign.

so, the correct possible hypothesis test is option D, in which alternative hypothesis denotes the not equal to sign which is correct or possible to test.

D: population parameter = constant vs. population parameter constant
