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 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. Participants are then all given the same 10-item test on the material. Their scores appear below. Scores on the test represent interval-ratio data and are normally distributed. music no-music 6 10 5 9 6 7 5 7 6 6 6 6 7 8 8 6 5 9 Please use the appropriate statistical test to analyze these data, and design a hypothesis testing process, get the conclusion about whether students who study with music playing devote as much attention to their studies as do students who study under quiet conditions. If significant, compute the effect size, interpret this, and draw a graph representing the data.
