15. An experiment was designed to test whether or not students can tell the difference between tap water and bottled water. For cach student in a class of 20 students, three cups of water will be used. Two of the cups will be filled with either tap water or bottled water and the final cup filied with the other type. The students will drink all three cups of water and will be asked to identify which cup of water was different from the others. The type of water to be poured in two of thc three qups will be determined by random assignment. Which of the following cannot bc uscd to randomly assign each student to either two cups of tap water and one cup of bottled water or two cups of bottled water and one cup of tap water? Put each studcnt's name on cqually sized pieces of paper and then put the names in a hat. Mix the names thoroughly. The first ten students sclccted will be given two cups of tap water and the other students will be given two cups of bottked water. Label each student with a different integer from 1 to 20. Usc the calculator's random number gencrator to select 10 different numbers. The first ten students selected will be given two cups of tap water and the other students will be given two cups of bottled a. b. water. Before the expcriment, ask the students if the typically drink tap water or bottled water. The students that typically drink tap water will be given will be given two cups of bottled water and the students that typically drink bottled water will be given will be given two cups of tap water. d. Give each student a 2-digit number from 01 to 20. Use a table of random digits and selcct two digits at a time until thcre are 10 numbers bectween 01 and 20, Ignore repeats and numbers larger than 20. C.
