101 Pert II-Mathematics as a Tool CHAPTER 4-Data Manage ment 2. . school keeps a record of drinks purchased from their cafe teria. The cata in the table shcw the purchases for the first eight days of school t roken down into lem on juice and choco r nilk purchases. Lemon Juice 25 17 27 21 23 21 16 26 Choco Milk 10 16 9 15 18 19 22 11 . Draw a box-and-v hisker plot for the lemon juice purchases. EB. Draw a box-and-v hisker plot for the clhoco milk purchases. C. What is the median for lemon juice purchases? Choco milk purchases? D. How do the data sets differ? 3. 1: is hypothesized that there are fluctu ations in norepineplırine (NE) T5vels which accomp any fluctuations in affect with bipola affective cisorder (manic-depiessive illness). Thu s, during depressi re states, HE levels drop; duri ng manic states, NE levels increase. To test this relationship, researchers measured the level of NE by meas uring the 1netabolite 3-methoxy-4-hydroxyphenylgly ol (MHPG in micro gram per 4 hour) in the patient's urine experiencing varying levels of mania/ cepression. Increased levels of MHPG are correlated with increased 1netabolism (thus higher levels) of central nervous system IHE. Levels (f mania/depression were also recorded on a scale with a low score i ndicating increased nania and a high score increased depre ssion. The cata is provided be ow. http://faculty.webster.edu/woolfim/9danswer. html MHPG Affect 980 22 26 1209 1403 8 1950 1814 10 1280 1073 1066 19 26 12 880 23 776 28 A. Compute the correl ation coefficient. B. What does this statistics mean concerning the relationshi) between MHPG levels and a fect? C. What percent of the variability is acccunted for by the relationship between the two variables? (% of Var = 1?) D. What would be the slope and y-intercep: for a regression line based on these data? E. What would be the predicted affect score if the individual had an MHPG level of 1100? of 950? of 700?
