A study is conducted to determine the average tuition that undergraduate students in the UAE pay per semester. Each student in the following samples is asked how much tuition he or she paid for the fall 2020 semester. A. A sample of 100 undergraduate Aurak students is taken by organizing the students names by classification (freshman, sophomore, junior, or senior), and then selecting 25 students from each. B. A random number generator is used to select a student from the alphabetical listing of all undergraduate students in the University of Dubai in the fall semester. Starting with that student, every 50th student is chosen until 75 students are included in the sample. C. A completely random method is used to select 75 students in Ras Al Khaimah. Each undergraduate student in the fall semester has the same probability of being chosen at any stage of the sampling process. D. The freshman, sophomore, junior, and senior years are numbered one, two, three, and four, respectively. A random number generator is used to pick two of those years. All students in those two years are in the sample. E. A soccer coach selects six players from a group of boys aged eight to ten, seven players from a group of boys aged 11 to 12, and three players from a group of boys aged 13 to 14 to form a recreational soccer team. F. A high school educational researcher interviews 50 high school female teachers and 50 high school male teachers. G. A student interviewed his classmates in OPMT 211 class to determine how many pairs of jeans a student owns, on the average.
