To calculate the average value of a given set, you have to add all observations and divide it by the number of components of said set.
Using the formula
[tex]\frac{\Sigma x}{n}[/tex]∑x: represents the sum of observations
n= total number of components in the set.
For the first set you have three different observations of three different flights, the average for this set is:
[tex]\begin{gathered} \Sigma x=9+6+14=29 \\ \frac{\Sigma x}{n}=\frac{29}{3}=9.67f\exponentialE et \end{gathered}[/tex]The average distance was 9.67feet
For the second set, you have three observations:
[tex]\begin{gathered} \Sigma x=4+6+4=14 \\ \frac{\Sigma x}{n}=\frac{14}{3}=4.67f\exponentialE et \end{gathered}[/tex]The average distance was 4.67feet
Since theThe airplane flew on average a greater distance in the first time than in the second time.
