Assume somebody without a life labeled 6000 coins in the following manner: 1000 pennies from current circulation with whole numbers 0001 to 1000, 1000 nickels from current circulation with whole numbers 1001 to 2000, 1000 dimes from current circulation with whole numbers 2001 to 3000, 1000 quarters from current circulation with whole numbers 3001 to 4000, 1000 half-dollars from current circulation with whole numbers 4001 to 5000, and 1000 silver-dollars from current circulation with whole numbers 5001 to 6000. 1 pts Identify the type of sampling used to generate the random sample described below. Letting 1 = pennies, 2 = nickels, 3 = dimes, 4 = quarters, 5 = half-dollars, and 6 = silver-dollars. Form a sample of size 1000 by rolling a 6-sided number cube exactly once, and put all of the type of coin that corresponds to the number on the cube in the desired sample. systematic O simple random O multi-stage O cluster O stratified
