If the outcome is heads, the sample is taken to be the 150 students with a 'l° 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?
