Answer: Using Chi-square.
Step-by-step explanation: To check if the provided data show any differences in preference for the two detergents (i.e., two variables), a Chi-square can be deployed, as it is used to test the goodness of fit, and test if two variables are related.
If the value obtained is less than 0.05, it means that there is statistical difference between the preference for the two detergents.
However, if the obtained value is higher than 0.05, it translates that there is no statistical difference between the preference for the two detergents.

Wild grove to lakewood:
21^2 + 72^2 = x^2
441 + 5184 = x^2
5625 = x^2
75 = x
Home to Lakewood: 72
Lakewood to wildgrove: 75
Wildgrove to home: 21
72+75+21= 168 kilometers
