Answer :

Below is a detailed explanation of the solution:

1. For the first statement, "Speeding has no effect on braking distance."
  - In reality, when a vehicle is speeding, the brake system must work harder and the braking distance increases compared to lower speeds. This means that speeding does affect braking distance.
  - Therefore, the statement is false and the correct option is the second one.

2. For the second question, "In 2021, ______ percent of vehicle occupants reported to have been using restraints at the time of a traffic crash were totally ejected from the vehicle."
  - Among the available choices, data indicates that about $5\%$ of the restrained occupants were totally ejected.
  - Hence, the correct answer is the second option.

3. For the third question, "What are the economic costs attributable to distracted driving annually?"
  - The economic costs from distracted driving are estimated at approximately \$36 Billion per year based on the commonly reported figures.
  - This corresponds to the first option.

Thus, the final answers for the three questions are:
$$ (2,\; 2,\; 1) $$

This means:
- Question 1: Option 2 (False)
- Question 2: Option 2 ($5\%$)
- Question 3: Option 1 (\$36 Billion)
