A. The percentage of the survey respondents that do not like both hamburgers and burritos is 26.34%.

B. The marginal relative frequency of all customers who like hamburgers is 53.66%.

C. Using the conditional relative frequencies of the data point, the strongest association of its two factors shows liking hamburgers and not liking burritos is the case.

Data and Calculations:

The completion of the table for the data analysis is as follows:

                          Likes Hamburgers   Does not like Hamburgers    Total

Likes burritos                    29                                41                           70

Does not like burritos       81                                54                         135

Total                                  110                               95                        205

A. The percentage of the survey respondents that do not like both hamburgers and burritos is 26.34% (54/205 x 100).

B. The marginal relative frequency of all customers who like hamburgers is 53.66% (205 - 95)/205 X 100.

C. The conditional relative frequencies:

Likes of hamburgers = 53.66% (110/205 x 100)

Dislikes of hamburgers = 46.34% (95/205 x 100)

Likes of burritos = 34.15% (70/205 x 100)

Dislikes of burritos = 65.85% (135/205 x 100).

Thus, we can conclude that based on the conditional relative frequencies more customers of the food truck like hamburgers (53.66%) compared to those who like burritos (34.15%).
