(a) The speed of a car (measured in mph ) defines a continuous random variable. (b) The size of a file (measured in kilobytes) defines a discrete random variable. (c) Suppose we expect to see an average of 50 meteorites in the sky one night. The number of meteorites actually observed can be modeled by a binomial distribution. (d) The wait time between two occurrences of a Poisson process can be modeled using an exponential distribution. (e) The number of fatalities resulting from airline accidents in a given year can be modeled using a Poisson distribution. (f) Suppose during an 8 hour shift a person expects a phone call to arrive at a time that is uniformly distributed during their shift. The probability the phone call arrives during the last half hour equals 6.25%.
