In a standard 52-card deck, where each card is assigned a numeric value, the mean of the 52 cards is 7.0 with a standard deviation of 3.742. To test if a representative sample can be attained, the deck is shuffled and 13 cards are randomly drawn, one at a time. Each card is recorded and then returned randomly to the deck before the next card is drawn. This process of drawing 13 random cards is repeated a total of 20 times, and the mean and standard deviation of each round is computed. Which...
