Given the data provided, our goal is to determine which nationality of maids provides the greatest value in terms of financial stability and retention for our company, and which nationality might be less beneficial to hire due to higher turnover rates and associated costs. We have collected data from 1200 Ethiopian maids, 2150 African, and 1080 Filipinas we interviewed. The successful hiring rates were 500 per 1000 for Ethiopians, 700 per 1000 for Africans, and 800 per 1000 for Filipinas. After hiring, we categorized the financial impact of a maid leaving based on how long they stayed with us: Leaving in less than 6 months incurs a loss of 80% of the hiring cost. Leaving between 6 months to a year incurs a loss of 40% of the hiring cost. Leaving between a year and a year and a half incurs a loss of 20% of the hiring cost. The number of maids leaving within these categories is as follows: Ethiopian maids: 35 left in under 6 months, 30 left between 6 months to a year, and 50 left between a year to a year and a half. African maids: 75 left in under 6 months, 80 left between 6 months to a year, and 105 left between a year to a year and a half. Filipina maids: 90 left in under 6 months, 85 left between 6 months to a year, and 65 left between a year to a year and a half. Considering the hiring rates, the time periods the maids stayed, and the financial losses incurred when they left, which nationality of maids appears to offer the best return on investment for our company? Conversely, which nationality appears to be less advantageous to hire, from a financial perspective? Please explain your
