Answer:

Yes, the given analysis involves a statistical test. Population parameter of interest = '% of community people living in mobile homes' (MH)

H0 : MH = 0.09
H1 : MH > 0.09

Step-by-step explanation:

Hypothesis testing is a statistical test, of testing an assumption (statement) about population parameter.

Null Hypothesis [H0] is a neutral statement of 'no difference' about a population parameter; stating variable is no different than its mean.

Alternate hypothesis [H1] is the 'specific difference' stating hypothesis about a population parameter; contrary to the null hypothesis.

To determine if there is evidence for the claim that the percentage of people in the community living in a mobile home is greater than 9% :

This analysis can be done by using statistical test : one sided 't' test. The population parameter of interest would be '% of community people living in mobile homes' (MH)

H0 : MH = 9% → MH = 0.09
H1 : MH > 9% → MH > 0.09
