Question

Four students did a survey to find the soda flavor sixth-grade students prefer. The table below shows the method each student used to conduct the survey:

Trey: Asked 100 students at random from his seventh-grade class what their favorite soda flavor is
Jesse: Asked 100 sixth-grade students at random what their favorite soda flavor is
Nita: Asked 100 eighth-grade students at random what their favorite soda flavor is
Ruben: Asked 100 third-grade students at random what their favorite soda flavor is

Which student's survey is most likely not biased? (1 point)
A. Trey
B. Jesse
C. Nita
D. Ruben

Answer 1

B. Jesse, since he surveyed only sixth-grade students, which is the target population for the survey. The other students surveyed students from different grade levels, which could introduce bias into the results.

Answer 2

The survey that is most likely not biased is Jesse's survey. Jesse asked 100 sixth-grade students at random what their favorite soda flavor is. By selecting the participants randomly from the specific target group (sixth-grade students), Jesse's survey is less likely to be influenced by factors such as age or grade level that could introduce bias into the results. Therefore, the answer is B. Jesse.
