Question1: The population will consider of 10 regular decks of cards well shuffled..

As described, we randomly draw 100 cards from the population and record a sample (D - diamond card, ND - not diamond card}. In the sample we have 24 diamond cards and 76 of the other suite.

Answer the following questions:

Number of elements in the population is ?

Number of elements in the sample is ?

Proportion of diamond cards in the sample is (express it as a decima)?

Question2: We can use the methods used in this class for finding confidence interval because all assumptions are satisfied. Namely,

1) the sample is random.

2) the values in the sample are independent.

3) np ? and n(1-p) ?

where n- sample size; p -sample proportion
