A study conducted in a certain period of time found that fewer than half of employers who hired new college graduates last academic year plan to definitely do so again. Suppose that the hiring intentions of the respondents were as follows: 37% selected Surely Hire 22% selected Probably Hire 21% selected Hire Unsure 20% selected Do Not Hire Six month later, a random sample of 100 employers were asked about their hiring intentions and gave the following responses: . 42 selected Surely Hire 0 13 selected Probably Hire - 28 selected Hire Unsure . 17 selected Do Not Hire At 2.5% significance level, does it mean that proportions from the initial study have significantly changed? Use Goodness-of-Fit test and x2 distribution. (0 - E)2 For part (a), round your answers in the " T" column to 3 decimal places. (a) Fill in the table below. (a) Fill in the table below.
