Question 4 The National Institute of Mental Health published an article stating that in any one-year period, approximately 8.3% of American adults suffer from depression or a depressive illness. Suppose that in a survey of 2000 people in a certain city, 11.5% of them suffered from depression or a depressive illness. Conduct a hypothesis test to determine if the true proportion of people in that city suffering from depression or a depressive illness is more than the 8.3% in the general adult American population. Test the relevant hypotheses using a 5% level of significance. Give answer to at least 4 decimal places. a. What are the correct hypotheses? (Select the correct symbols and use decimal values not percentages.) Ho: Select an answer? H₁: Select an answer? b. Based on the hypotheses, find the following: c. Test Statistic = d. p-value = e. Based on the above we choose to Select an answer f. The correct summary would be: Select an answer that the true proportion of people in that city suffering from depression or a depressive illness is more than the percent in the general adult American population of 8.3%. 34 % 5
