Answer :

In order to test if the supervisor's county is different from the United States average, she will perform a two tailed test.

Here we are given the following data-

number of observations in the sample n = 795

observed value x = 150

and proportion p = 0.155

We need to test whether proportion is different from 15.5 % or not.

Thus, we will do a two tailed test with hypothesis as follows -

Null hypothesis H₀ ⇒ p = 0.155

Alternate hypothesis Hₐ ⇒ p ≠ 0.155

Hence, in order to test if the supervisor's county is different from the United States average, she will perform a two tailed test.
