Due to the high crime rate in Mexico City, a study was made regarding small stores that could accept debit cards in the payment of consumers, of which it was found that 58% would accept it, calculate the probability that in a random sample than 80 stores a) 48 more are willing to accept debit cards b) between 44 and 60 stores are willing to accept debit cards c) The banks interested in contributing with the card services assure that in those samples less than 43 stores would agree with a probability lower than 5%, what is the minimum size that they would have to choose a sample to corroborate this statement?
