Firstly, the information around the number of utility damage reported as well as the projects carried out in 2019 was represented on a scatter plot (see Figure 3). The scatter plot shows a trending linear partnership meaning that the greater the amount of projects handled the a lot more the damages reported. Additionally, a ttest statistic was performed to compare the utility harm report and total projects carried out in 2019. The results presented in Table five are based on the positiv.
