B.) Data from a completely randomized design are shown in the following table.
For a one-way ANOVA, the Between Sum of Squares is ________.
a.) 36.17
b.) 28.75
c.) 64.92
d.) 18.03
e.) 28.04
C.) For the following ANOVA table, the MS Treatment value is ___________.
a.) 150
b.) 50
c.) 450
d.) 3.49
e.) 40
D.) The head of the math department at a local community college is interested in conducting an experiment to determine effective teaching strategies for improving student math comprehension and math literacy. In particular, she is interested in a new pedagogical model called “flipped classroom,” in which the typical lecture and homework elements of the course are reversed. Short video lectures are viewed by students at home before the class session, while in-class time is devoted to exercises, projects, or discussions. For this purpose, the math head will have half of the sections of Calculus II this coming semester be taught in the traditional setting, while the other half will use the flipped classroom model. In this experiment, the independent variable has ______ levels.
a.) 0
b.) 0.5
c.) 1
d.) 1.5
e.) 2
E.) Data from a completely randomized design are shown in the following table.

a.) 36.17
b.) 28.75
c.) 64.92
d.) 64.92
e.) 28.04
