EACH QUESTION MUST BE COMPLETELY FINISHED WITH WORK SHOWN. EACH QUESTION HAS DIFFERENT SUBPARTS WHICH ARE ALPHEBETICALLY CATAGORIZED, EACH PART MUST BE COMPLETED AND ALL WORK MUST BE SHOWN. 1.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 participates to either the music or non-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 MUSIC NO MUSIC 6 10 5 9 6 7 5 7 6 6 6 6 7 8 8 6 5 9 A) What statistical test should be used to analyze these data? B) Identify H0 and Ha for this study C) Conduct the appropriate analysis D) Should H0 be rejects? 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 2. The researcher in exercise 2 decides to conduct the same study using a within- participants design to control for differences in cognitive ability. He selects a random sample of subjects and has them study different material of equal difficulty in both the music and no music conditions. The study is completely counterbalanced to control for order effects. The data appear next. As before, they are measured on an interval- ratio scale and are normally distributed; he believes that studying under quiet conditions will lead to better performance.

If significant, compute the effect size). If significant, compute the effect size. F). If significant draw a graph representing the data. 3. Researchers at a food company are interested in how a new spaghetti sauce made from Green tomatoes (and green in color) will compare to their traditional red spaghetti sauce. They are worried that the green color will adversely affect the tastiness scores. They randomly assign subjects to either the green or red sauce condition. Participants indicate the tastiness of the sauce on a 10-point scale. Tastiness scores tend to be skewed. The scores follow: RED SAUCE GREEN SAUCE 7 4 5 5 9 6 10 8 6 7 7 6 8 9 A) What statistical test should be used to analyze these data? B) Identify H0 and Ha for this study. C) Conduct the appropriate analysis D) Should H0 be rejected? What should the researcher conclude?
