A Researcher Investigated Whether a Student's Seat Preference Was Related

question 165

Short Answer

A researcher investigated whether a student's seat preference was related in any way to the gender of the student. The researcher divided a lecture room into three sections (1-front, middle of the room, 2-front, sides of the classroom, and 3-back of the classroom, both middle and sides) and noted where each student sat on a particular day of the class. The researcher's summary table is provided below. $\begin{array}{l|ccc|c} & \text { Area 1 } & \text { Area 2 } & \text { Area 3 } & \text { Total } \\\hline \text { Male } & 16 & 8 & 9 & 33 \\\text { Female } & 13 & 10 & 16 & 39 \\\hline \text { Total } & 29 & 18 & 25 & 72\end{array}$

Suppose a person sitting in the front, middle portion of the class is randomly selected to answer a question. Find the probability that the person selected is female.
A) $\frac { 13 } { 29 }$

B) $\frac { 1 } { 3 }$

C) $\frac { 29 } { 39 }$

D) $\frac { 13 } { 72 }$

• A) \(\frac { 13 } { 29 }\)
• B) \(\frac { 1 } { 3 }\)
• C) \(\frac { 29 } { 39 }\)
• D) \(\frac { 13 } { 72 }\)
