To get some County-level information about whether people were financially impacted due to Covid-19, a sample of 200 adults in Allegheny county is surveyed to test if a minority (less than half 50%) has been financially impacted. we find that 92 adults in the study have been financially impacted.

1- how many variables are there in the study, what are they? and what is the most appropriate statistical test? (test for proportion, test for mean, regression, etc...)

2- for the appropriate test selected in question 1, write the hypothesis, calculate the test statistic and p-value, and state a formal conclusion (alpha significance 0.05). make sure you show your calculations.
