In the Sanatorium For Acute Intellectual Malnutrition, a nourishing twelve course Christmas Exam is finally administered to 20 starving statistics orphans who are seated in a circle. Having been deprived to the point of not feeling hungry, each student randomly shoves the exam to the fellow on his right or the one on his left. How many orphans on average will end up without a test?

An experimenter investigated the effects of blue light exposure on people’s sleep quality. Researchers get 50 people and randomly assign 25 people to be exposed to blue light for 20 min. before bed and the other 25 people to have no blue light exposure 25 min. before bed. Each participant is sent to bed at 10pm and woken up at 7am the next morning. When all participants are woken up, they must fill out a sleep quality questionnaire. The scores seen below represent participants’ sleep quality ratings where higher numbers indicate better sleep quality. Does the blue light exposure negatively impact sleep quality?

"Snoqualmie" is a name shared by a waterfall and a tribe of Native Americans. In a study of the cultural importance of the waterfall, two groups of the Snoqualmie tribe were randomly surveyed. One group consisted of Snoqualmie members living less than 25 miles from the waterfall. Another group consisted of Snoqualmie members living more than 25 miles from the waterfall. The researchers asked each member to rate the cultural importance of the waterfall as low, medium, or high. Data from the study are presented in the following table. Members Living More Than 25 Miles from the Waterfall Members Living Less Than 25 Miles from the Waterfall Total Low 25 17 42 Medium 8 21 29 High 12 17 Total 38 50 88 If the distributions of ratings are the same for those Snoqualmie members living less than 25 miles from the waterfall and those living more than 25 miles from the waterfall, which of the following is equal to the expected count of members living less than 25 miles from the waterfall who rated…
