Statistical tests/ Descriptive Analysis
The dependent variables in this case context would include the operational flexibility of the UAVs, human factors, and delivery time. The table below suggests a statistical description of the challenges associated with the effectiveness of MQ-8B Fire Scout to provide humanitarian efforts for post-natural disasters. The previously projected data was an estimation, although the data gathered reflects real-world application in describing the data in this research.

Note. Mean, Min, Max, and SD are measured in minutes. Min = Minimum, Max = Maximum, SD = Standard Deviation. Data from 2012-2016 were used for this analysis.
T statistics: An independent t-test is a two-sample t-test used to determine whether there is a statistically significant difference between the means in two unrelated groups.
The data selections come from the normal population.
The following hypothesis (H) has been formulated for the study:
H0: There is no statistical difference in safety when using the Northrop Grumman MQ-8B Fire Scout when compared to manned vehicles to provide humanitarian aid in areas affected by a disaster.
H1: There is a statistical difference in safety when using the Northrop Grumman MQ-8B Fire Scout when compared to manned vehicles to provide humanitarian aid in areas affected by a disaster.
Level of significance is 0.05

Decision: Fail to reject the null hypothesis because the P-value is greater than 0.05 and concludes: There is no statistical difference in safety when using the Northrop Grumman MQ-8B Fire Scout when compared to MH-60 to provision humanitarian aid in areas affected by a disaster.
Microsoft Excel was used to organize the data of different UAVs for conducting various humanitarian aid operations. SPSS software was used SPSS to conduct a descriptive analysis.
