A study found that fewer than half of employers who hired fresh college graduates last academic year plan to definitely do so again. Suppose the hiring intentions of the respondents were as follows: (You may find it useful to reference the appropriate table: chi- square table or Etable) Definitely Likely to Hire Hire Uncertain 281 Will not Hire Hire 378 178 18 Six months later, a sample of 500 employers were asked their hiring intentions and gave the following responses: Definitely Likely to Hire Hire Uncertain 3ou TITM Hire Hire 170 100 120 110 a. Choose the appropriate alternative hypotheses to test whether the proportions from the initial study have changed. O All population proportions differ from their hypothesized values. At least one of the population proportions differs from its hypothesized value. b-1. Colculate the value of the test statistic. (Round the intermediate calculations to at least 4 decimal places and final answer to 3 decimal places.) Tost statistic
