According to the WHO Global Ambient Air Quality Database, the most impacted are populations in low-income regions, with 97% of cities in low- and middle- income countries with more than 100,000 inhabitants not meeting WHO air quality guidelines. In high-income countries, it is 49% of the cities. The AQI-NY data file contains information on the air quality index (AQI) in New York for the first 6 months of 2018. The air quality is considered “good” if the AQI is at most 50, and “moderate” if the AQI is between 51 and 100. Otherwise, the concentration of pollutants may affect the health of at least the most sensitive people. The New York State Department of Health states that the percentage of days with “unhealthy” AQI has to be less than 8% to meet the goals established by the government. You are hired by this department to assess if the goals are being met. To do this, you will first need to obtain a subset of the data file using the capabilities of your statistical analysis computer program. Use the data file AQI-NY as the basis for your statistical analysis.
