Last year,a comprehensive report stated that 27% of businesses in northeast of Ohio were considered highly profitable. This year, based on a sample of 46 business owners, a survey your team conducted indicated that 23 businesses were highly profitable. Would you conclude that the proportion of businesses that are highly profitable increased or decreased from last year with a statistical significance? Use a statistical hypothesis test to determine this, using a 1% significance level. (Note from the Instructor - Think about this concept for your studying purposes) For you answer in this problem - give the calculated test statistic you would come up with in step 5 of the hypothesis testing process.
