(a) Number of traffic fatalities per year in the state of Florida (b) Distance a golf ball travels after being hit with a driver (c) Time required to drive from home to college on any given day (d) Number of ships in Pearl Harbor on any given day (e) Your weight before breakfast each morning 2. Statistical Literacy Which of the following are continuous variables, and which are discrete? (a) Speed of an airplane (b) Age of a college professor chosen at random (c) Number of books in the college bookstore (d) Weight of a football player chosen at random (e) Number of lightning strikes in Rocky Mountain National Park on a given day 3. Statistical Literacy Consider each distribution. Determine if it is a valid probability distribution or not, and explain your answer. (a) x 0 1 2 P(x) 0.25 0.60 0.15 (b) x 0 1 2 P(x) 0.25 0.60 0.20 4. Statistical Literacy At State College all classes start on the hour, with the earliest start time at 7 A.M. and the latest at 8 P.M. A random sample of fresh- men showed the percentages preferring the listed start times. Start Time 7 or 8 A.M. 9,10, or 11 A.M. 12 or 1 P.M. 1 P.M. or later After 5 P.M. % preferring 10% 35% 28% 25% 15% Can this information be used to make a discrete probability distribution? Explain.
