MATH 399 COURSE PROJECT 1

MATH 399 COURSE PROJECT 1Course Project 1 MATH339 The topic that I have chosen is the graduation rates of US high schools for the year (“High School Graduation Rates by State 2019”, 2019). The data is found from World Population Review and lists the graduation rates as a percentage for each state. Only public schools are considered within the data as information from private schools are not accessible since they are not run by the government. Sample Data 89.3 78.2 78 88 82.7 79.1 87.9 86.9 82.3 80.6 82.7 79.7 87 83.8 91 86.5 89.7 78.1 86.9 87.7 88.3 80.2 82.7 83 88.3 85.8 89.1 80.9 88.9 90.5 71.1 81.8 86.6 87.2 84.2 82.6 76.7 86.6 84.1 83.6 83.7 89.8 89.7 86 89.1 86.9 79.4 89.4 88.6 86.2 Table 1.
