Quizplus · Accepted Answer

The proportion of times an even number will show up on a single roll of a six-sided die is 1/2 (there are three even numbers out of six possible outcomes). The center of the sampling distribution for the proportion of even numbers in 60 rolls will be the population proportion, which is also 1/2. Therefore, the answer is C, 1/2.
