Activity 2. Consider sampling the 300 students, in a different way, to obtain a sample of 150 stu-dents. Alongside each name, the numbers 1 and 2 are listed alternately (1, 2, 1, 2, ...). A fair coin is tossed. If the outcome is heads, the sample is taken to be the 150 students with a '1' next to their name. If the outcome is tails, the sample is the 150 students with a '2' next to their name. a. Using this method, how many possible samples of 150 can be obtained? b. Does every student have the same chance of selection? c. Is this a simple random sample?
