Vail Resorts tracks the proportion of seasonal employees who are rehired each season. Rehiring a seasonal employee is beneficial in many ways, including lowering the costs incurred during the hiring process such as training costs. A random sample of 833 full-time and 386 part-time seasonal employees from 2009 showed that 434 full-time employees were rehired compared with 189 part-time employees.
(a) Is there a significant difference in the proportion of rehires between the full-time and part-time seasonal employees? Use α = .10 for the level of significance.
(b) Use Excel to calculate the p-value.
