In spite of an unemployment rate of 26% and an economy in crisis, 70% of people in a certain country responded that they were in favor of keeping the euro rather than returning to their original currency. A random sample of 33 people from the country was selected. Use the normal approximation to the binomial distribution to answer parts a through e. a. Calculate the mean and standard deviation for this distribution. The mean is 23.1. (Round to four decimal places as needed.) The standard deviation is 2.6323. (Round to four decimal places as needed.) b. What is the probability that 20 or more people in the sample are in favor of retaining the euro? The probability is (Round to four decimal places as needed.)
