question 30

Essay

In team-teaching, two or more teachers lead a class. An researcher tested the use of
team-teaching in mathematics education. Two of the variables measured on each sample
of 165 mathematics teachers were years of teaching experience x and reported success rate
y (measured as a percentage)of team-teaching mathematics classes.
a. The researcher hypothesized that mathematics teachers with more years of experience
will report higher perceived success rates in team-taught classes.
State this hypothesis in terms of the parameter of a linear model relating x to y.
b. The correlation coefficient for the sample data was reported as r = -0.31.
Interpret this result.
c. Does the value of r support the hypothesis? Test using α = .05.
