<span>In the highway transportation system, pedestrians are people who walk, so they would not be called drivers. Therefore the answer is not low risk drivers or youthful drivers. The phrase "beginning users" refers to people who are just in the early stages of learning something or using something. In general, this phrase would not necessarily be used to describe pedestrians, drivers, or cyclists. The only remaining answer is "roadway users", which makes perfect sense. Pedestrians, drivers, and cyclists are people who are using the roadway, therefore they are roadway users.</span>

Answer:
confounding variable; lowered.
Explanation:
In the field of statistical analysis, a <u>confounding variable</u> is one that influences both the independent variable and the dependent variable. When an experimented is designed, the researcher wants to study the effect the independent variable has on the dependent variable. However, if there's a third variable that can influence them, it can cause a spurious correlation.
The psychologist wanted to test the effects using the new computer program (independent variable) had in helping students learn math (dependent variable). But when she divided the group in two, separating them by gender, she introduced a third variable (confounding variable) that wasn't accounted for when designing the experiment and that can influence either variable. <u>Because of this, the internal validity of the study has been </u><u>lowered</u><u>.</u>
