Project #72937 - A statistics problem

The student in question 4 from module 13 decides to conduct the same study using a within-subjects design in order to control for differences in cognitive ability. He selects a random sample of participants and has them study different material of equal difficulty in both the music and no music conditions. The data appear below. As before, they are measured on an interval-ratio scale and are normally distributed.

 

Music: 6,7,6,5,6,8,8

No music: 10,7,8,7,7,9,8

 

A.) What statistical test should be used to analyze these data? (what type of t test)

B.) Identify Ho and Ha for this study

C.) Conduct the appropriate analysis

D.) Should Ho be rejected? What should the researcher conclude?

E.) If significant, compute he effect size and interpret.

F.) If significant, draw a graph representing the data
