Answer:
True statements:
A. The relative frequency of rolling 4 is 
E. The experimental probability of rolling 1 is less than the experimental probability of rolling 6.
Step-by-step explanation:
Nathan made 11 + 16 + 14 + 20 + 12 + 17 = 90 rolls altogether. Consider all options:
A. The relative frequency of rolling 4 is

This option is true.
B. The experimental probability of rolling 3 is
The theoretical probability of rolling 3 is
therefore, the experimental probability of rolling 3 is less than the theoretical probability. This option is false.
C. The experimental probability of rolling 2 is
and the theoretical probability of rolling 2 is
The experimental probability of rolling 2 is smaller than the theoretical probability of rolling 2. Option C is false.
D. The relative frequency of rolling 5 is
This option is false.
E. The experimental probability of rolling 1 is
and the experimental probability of rolling 6 is
Since
then the experimental probability of rolling 1 is less than the experimental probability of rolling 6. This option is true.
F. The theoretical probability of rolling 1 is the same as the theoretical probability of rolling 6. This option is false.
