Question
For each random variable defined here, (i) indicate if it is discrete or continuous, and (ii) write the
set of possible values for the variable (e.g., possible values of X are 0<x<∞, or possible values of X
are {1, 2, 3, ...}).
a.
W = Number of boreholes drilled at a site
b. X = Maximum load on a bridge in a day (lbs/ft)
C.
Y = Number of accidents on Main Street in Newark DE in a year
d. Z = Amount above or below budget that a construction project ends up costing (dollars)
