The figure displays the density curve of a
uniform distribution.
W
0
This curve takes the constant value 1 over the interval from
0 to 1 and is 0 outside that range of values. This means that
the data described by this distribution have values that are
uniformly spread between 0 and 1. Use areas under this
density curve to answer the questions.
what percent of the observations lie above 0.4?
