A student is interested in whether students who study with music playing devote as much attention to their studies as do students who study under quiet conditions (he believes that studying under quiet conditions leads to better attention). he randomly assigns participants to either the music or no-music condition and has them read and study the same passage of information for the same amount of time. Subjects are given the same 10-item test on the material. Their scores appear next. Scores on the test represent interval-ratio data and are normally distributed.

Scores (shown in book as vertical columns) with Music: 6,5,6,5,6,6,7,8,5. Scores (shown in book as vertical) without Music: 10, 9,7,7,6,6,8,6,9.

A) what statistical test should be used to analyze these?
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 and interpret the effect size.
F) If significant, draw a graph representing the data.
G) Determine the 95% confidence interval.
