A simple random sample of n subjects is selected in such a way that every possible sample of the same size n has the same chance of being chosen.​ (A simple random sample is often called a random​ sample, but strictly​ speaking, a random sample has the weaker requirement that all members of the population have the same chance of being​ selected.) Determine whether each of the following is a simple random sample​ and/or a random sample. Complete parts​ (a) through​ (c). Question content area bottom Part 1 a. In a recent​ year, the following medical schools had the given​ enrollments: New York University​ (103), Columbia​ (140), and New York Medical College​ (219). The names of those three colleges are printed on three separate index​ cards, the cards are​ shuffled, and one card is drawn. The sample consists of the names of the medical students enrolled in the selected medical school. This sample ▼ is is not a simple random sample. It ▼ is is not a random sample. Part 2 b. For the three medical schools in part​ (a), the 462 names of the students are printed on 462 index​ cards, then the cards are shuffled. Forty different cards are​ selected, and the sample consists of the 40 selected medical students. This sample ▼ is not is a simple random sample. It ▼ is is not a random sample. Part 3 c. For the three medical schools in part​ (a), a sample is constructed by selecting the 40 youngest medical students. This sample ▼ is not is a simple random sample. It ▼ is not is a random sample. Listed below are amounts of​ strontium-90 (in​ millibecquerels, or​ mBq) in a simple random sample of baby teeth obtained from residents in a region born after 1979.
