Example 1: Classify the following random variables as discrete or continuous and specify the domain/support of each random variable.
V = number of unbroken eggs in a randomly selected carton (dozen)
W = length of time between accidents at a factory
Y = whether or not you pass this class
Z = number of aircraft arriving tomorrow at STL.
V - discrete random variable
Domain : Carton of unbroken eggs i.e. (0,1,2,...)
W - Continuous random variable
Domain : time interval between accidents, length of interval may vary.
Y - discrete random variable
Domain : Class i.e. (pass, fail)
Z - discrete random variable
Domain : aircraft arriving tomorrow at STL
i.e. (0,1,2,...)

(b) 2] Amount of snow (in inch) of the next snow storm in Ottawa (c) 2] Daily exchange rate of Canadian dollar versus US dollar (d) 2 The number of car accidents in Ottawa area tomorrow 2. The number of times Ann used...
Which of the following variables are best thought of as continuous, which discrete? Indicate your choice for each by checking the appropriate column Variable Discrete Continuous (a) The actual length of a roll of plastic wrap advertised to be 30 feet long (b) The intensity of a 1000-Hz tone judged by a participant to be "equally as loud as" a 500-Hz tone of 50 decibels (c) In an experimental study, the participant's estimate for the height of a 3-meter image...

Problem 1 A Poisson process is a continuous-time discrete-valued random process, X(t), that counts the number of events (think of incoming phone calls, customers entering a bank, car accidents, etc.) that occur up to and including time t where the occurrence times of these events satisfy the following three conditions Events only occur after time 0, i.e., X(t)0 for t0 If N (1, 2], where 0< t t2, denotes the number of events that occur in the time interval (t1,...
