Answer:

C

Step-by-step explanation:

Khan

Considering that we want to test if the support for the opponent has decreased, the appropriate set of hypotheses for their significance test is given by:

C.

[tex]H_0: p = 0.45[/tex]

[tex]H_1: p < 0.45[/tex]

What are the hypothesis tested?

At the null hypothesis, we test if the support for the opponent has not decreased, that is, it still is of 45%, hence:

[tex]H_0: p = 0.45[/tex]

At the alternative hypothesis, we test if the support has decreased, that is, it is less than 45%, hence:

[tex]H_1: p < 0.45[/tex]

Hence option C is correct.
