In 2010, Dr. Bob decided to gather research on the type of disorders that present among his patients. His data collection resulted in the following breakdown of patients by disorder: 54.9% Schizophrenia; 21.1% Major Depression; 7.9% Obsessive-Compulsive Disorder; 4.5% Anxiety Disorder; 2.9% Personality Disorder; 8.8% Other. Information was collected from a random sample Of 300 patients in 2018 to determine whether or not the data has changed significantly. The sample data is given in the table below. At the a = 0.10 level of significance, test the claim that the disorder breakdown of patients at Dr. Bob's hospital has not changed significantly since 2010. Which would be correct hypotheses for this test? O Ho: P1 = P2; H₁: P₁ P2 © Hạ: 1 = #2; H: #2 O Ho: The breakdown of patients by disorder has changed significantly since 2010 (i.e. the given distribution no longer fits); H₁: The breakdwon of patients by disorder has not changed significantly since 2010 (i.e. the given distribution still fits) O Ho: The breakdown of patients by disorder has not changed significantly since 2010 (i.e. the given distribution still fits); H₁: The breakdown of patients by disorder has changed significantly since 2010 (i.e. the given distribution no longer fits) Type of disorder per patient in sample: Disorder Schizophrenia Major Dispression Obsessive-Compulsive Disorder Anxiety Disorder Personality Disorder Other Test Statistic: Give the P-value: Which is the correct result: Count 141 76 29 8 11 35 Do not Reject the Null Hypothesis Reject the Null Hypothesis Which would be the appropriate conclusion?
