From a deck of cards (which may or may not be a regulation deck), you take 52 samples. That is, you…a)

pick a random card and look at it

b) decide if its an ace or not

c) replace card and shuffle

d) repeat 52 times.

Out of the 52 samples, 7 were successful, in that they were aces

Now, determine a range for the number of aces in the deck with 98% confidence.

Hint: This is a binomial experiment dealing with PROPORTIONS (proportion of successes). Once you’ve determined the confidence interval as a percentage, multiply the left and right endpoints by 52 and round to determine the number of aces
