A population has four members (called A, B, C, and D). You would like to select a random sample of n=2, which you decide to do in the following way: Flip a coin; if it is heads, the sample will be items A and B; if it is tails, the sample will be items C and D. Although this is a random sample, it is not a simple random sample. Explain why. Question content area bottom Part 1 Choose the correct answer below. A. This is not a simple random sample because not every item has the same chance of selection as every other item. B. This is not a simple random sample because the N items in the frame were not partitioned into n groups of k items. C. This is not a simple random sample because the probability of selection for each individual item is unknown. D. This is not a simple random sample because not every sample of n=2 has the same chance of selection as every other sample of that size.
