Consumers spend an average of $13.80 on a meal at a restaurant in 2012. (Data extracted from www.alixpartners.com). Assume that the amount spent on a restaurant meal is normally distributed and that the standard deviation is $2. What is the probability that a randomly selected person spent more than $15? What is the probability that a randomly selected person spent between $10 and $12? Between what two values will the middle 95% of the amounts spent fall?
