Question 1177860: We know that proportion of diamond cards in a regular deck of cards is 13/52=0.25. Assume for a moment that we do not know it and we wish to use statistical methods to find a confidence interval for proportion of red cards in a deck. We will use 10 regular decks of card and select random sample of 100 cards.
Please use the above information to answer questions:

Question 1
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 decimal)

Hi
Number of elements in the population is: 10decks *52cards = 520
Number of elements in the sample is: 100
Proportion of diamond cards in the sample is (express it as a decimal)24/100 = .24
Wish You the Best in your Studies.
