Online Classes Are Becoming More and More Prevalent at the College

question 61

Short Answer

Online classes are becoming more and more prevalent at the college level. A statistics instructor randomly sampled ten students from his traditional face-to-face class and ten students from his online class to compare their comprehension of the material that was taught in the class. He administered the same final exam to each student and wants to use the Wilcoxon Rank Sum test to compare their exam scores. The results are shown below: $\begin{array}{c}\begin{array}{lll}\text { Traditional Class }\\82 \quad 91 \quad 75 \quad 68 \\93 \quad 85\quad 74 \quad 70 \\56 \quad 82 & & \end{array}\begin{array}{lll}\text { Online Class }\\67 \quad 66 \quad 72 \quad 73 \\77 \quad 76 \quad 48 \quad 81 \\86 \quad 92 & &\end{array}\end{array}$

Calculate the test statistic for the Wilcoxon Rank Sum Test.
A) $T _ { 1 } = 44$
B) $T _ { 1 } = 76$
C) $T _ { 1 } = 120$
D) $T _ { 1 } = 60$

• A) \(T _ { 1 } = 44\)
• B) \(T _ { 1 } = 76\)
• C) \(T _ { 1 } = 120\)
• D) \(T _ { 1 } = 60\)
