VSC The retirement ages of a group of steel workers are recorded below. Construct a histogram with 4 classes using Microsoft Excel, Google Sheets, or GeoGebra. You will upload the graph in the next question. {64, 60, 57, 63, 61, 64, 50, 62, 60, 56, 53, 62, 54, 60, 64, 53, 61, 58, 60, 64, 57, 56, 64, 61, 63} Use the data to answer the following questions. 1. What is the population mean of the data? 59.71 2. What is the population variance? b 14.9566 (Round to four decimal places. Note: s^2 means s?) 3. What is the population standard deviation? II 3.8674 Round to four decimal places) 4. The data is negatively skewed + 5. According to Chebyshev's theorem, at least 88.9% of the data falls between approximately 47.62 and (Round to the nearest hundredth.)
