Question
Middle school students were randomly sorted into one of two groups. Members of each group performed a series of mental tasks while music was playing in the background. One group listened to pop music and the other to country music. It is believed that music will impact the number of tasks completed. What can be concluded with α = 0.01? The results are below:
pop | country |
u1 = 34.34 | u2 = 49.25 |
σ1 =
4.08 |
σ2=6.48 |
n1 = 14 | n2 = 6 |
A) Condition 1:
Conditon 2:
B)Obtain/compute the appropriate values to make a decision about H0.
critical value=
test statistic=
Reject or Fail to Reject
C)Compute the corresponding effect size(s) and indicate magnitude(s).
d= / magnitude=
r2 = / magnitude =
