A random sample of 871 students between the ages of 20 and 24 at a large midwestern university completed a survey including questions about their sleep quality, moods, academic performance, physical health, and psychoactive drug use. Sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI), with students scoring less than or equal to 5 on the index classified as optimal sleepers, those scoring a 6 or 7 classified as borderline, and those scoring over 7 classified as poor sleepers. The table looks at the relationship between sleep quality classification and the use of over-the-counter (OTC) or prescription (Rx) stimulant medication more than once a month to help keep awake.

What do the data say about differences in sleep quality for those who use over-the-counter or prescription stimulant medication more than once a month to keep awake and those who don't? Those who use medications are more likely to have optimal sleep quality and less likely to have poor sleep quality than those who do not use medications. Those who use medications are less likely to have optimal sleep quality and more likely to have poor sleep quality than those who do not use medications.

Question
Give your answers to one decimal place and do not include the percent sign in your answers. Remember that there are two sets of conditional distributions for any two-way table. You are being asked to construct a table of the conditional distribution of sleep quality for each of the two drug-use groups. Use of OTC/Rx Meds to Wake < 1x/Month Optimal Borderline Sleep Quality on PSQI Index Poor Percentage 1 Percentage 2 Percentage 3 Percentage 4 Percentage 5 Percentage 6 Yes No Percentage 1: % Percentage 2: % Percentage 3: % Percentage 4: % Percentage 5: % Percentage 6: %
