A standard deck of cards has 52 cards. The cards have one of 4 suites: 13 cards are hearts, 13 cards are diamonds, 13 cards are clubs, and 13 cards are spades. We will draw cards from a shuffled deck of cards with replacement (after we draw each card, we will record the suite and put it back in the deck). We will keep going until we draw hearts. We wish to calculate the probability of having to draw 3 or fewer cards. Explain how you would choose random digits to simulate this scenario.

Question 2

Suppose that 90, 95, 98, and 99 confidence intervals are computed (using the same sample) for a population proportion. Which confidence level will give the narrowest interval?
a. 99
b. 98
c. 95
d. 90

Answer to Question 1

Generate random numbers between 1 and 4 . The 1 will represent hearts; the 2, 3, and 4 will represent the other suits. Every time we simulate this process, keep going until observing a 1 .
