Document Summary
7:59 pm: experiment: an activity in which there are at least two possible outcomes and the result of the activity cannot be predicted with absolute certainty. Roll a six-sided die and record the number that lands face up. We cannot say with certainty that the number face up will be a. 1, or a 2, etc. , so this activity is an experiment. Using a radar gun, record the speed of a pitch at a red sox baseball game. We"re not sure whether the pitch will be a fastball, curveball, slider, etc. And even if we steal the signal from the catcher, we cannot predict the speed of the pitch with certainty. Count the number of patients who arrive at the emergency room of a city hospital during a 24-hour period. Although past records might help us form an estimate, there is no way of predicting the exact number of emergency room patients during a 24-hour period.
