One of the most difficult things to do in statistics is to determine the correct hypothesis test to do for a given scenario. Determine the null hypothesis and the alternative hypothesis: ***=r***=r*tar***=r******=r***=r A Ham's Poi! conducted October 28, 2008 surveyed 2119 US adults who were asked "when you think of rising health care costs, who do you think is most responsible?\" One theory is that 50% of adults blame insurance companies, 10% blame pharmaceutical companies, 10% blame Federal and state governments, 10% blame hospitals, 10% blame physicians, 5% blame some other entity, and 5% are unsure who is most responsible.

Choose the correct Ho and HA statements: (A) Ho: Distribution of observed frequency percentages for healthcare blame DOES NOT FIT distribution of expected frequency percentages for healthcare blame (#) HA: Distribution of observed frequency percentages for healthcare blame FITS distribution of expected frequency percentages for healthcare blame ( B) Ho: Pexpected = Pobserved HA : Pexpected * PobservedO C) Ho: Distribution of observed frequency percentages for healthcare blame FITS distribution of expected frequency percentages for healthcare blame HA: Distribution of observed frequency percentages for healthcare blame DOES NOT FIT distribution of expected frequency percentages for healthcare blame (#) (D) Ho: Mexpected = Mobserved HA: Hexpected # Mobserved
