Does the expectation of good weather lead to more generous behavior? Psychologists conducted an experiment that studied the size of the tip in a restaurant when a message indicating that the next day's weather would be good was written on the bill. You work part-time as a server in a restaurant. You read a newspaper article about the study that reports that with 95% confidence the mean percentage tip from restaurant patrons will be between 21.33 and 23.09 when the server writes a message on the bill stating that the next day's weather will be good. Select the statement that determines whether or not you can conclude that if you begin writing a message on patrons' bills stating that the next day's weather will be good, then approximately 95% of the days you work your mean percentage tip will be between 21.33 and 23.09. O No, because the confidence interval only tells you about the mean tip from all restaurant patrons and nothing about the distribution of individual tips for a particular restaurant. Yes, because this was an experiment, so we can attribute cause and effect. No, because the restaurant where you work caters to undergraduate students. No, because that person is a better server than you are.
