The National Football League is made up of two conferences. the American Football Conference (AFC) and the National Football Conference (NFC). with an average ticket price of over $100 for the combined conferences. To compare average ticket prices between the two conferences. a random sample of 8 teams in the AFC and 10 teams in the NFC were randomly selected. The average ticket prices were compared and the 95% condence interval for the tme mean AFC ticket prices minus the true mean NFC ticket prices is (2.48. 6.37). Assume independent random samples were taken from populations that were normally distributed. Choose the best interpretation for the condence Interval in this problem. 0 We are '3596 condent that the true mean AFC ticket prices is lower than the true mean NFC ticket prices. 0 We are 9596 condent that there is no statisticailv signicant difference between the true mean AFC ticket prices and the true mean NFC ticket prices. 0 We are 95% condent that the true mean AFC ticket prices is higher than the true mean NFC ticket prices.
