A biostatistician is interested in studying the time X (in
seconds) it takes a hematology cell counter to complete a test on a
blood sample. The probability density function of the
aforementioned time is:
a) Find the cumulative distribution function and compute the
median and 65-th percentile of the time to complete a test on a
sample.
b) What is the percentage of tests require less than π/3 seconds
to complete?
c) Suppose that this biostatistician is interested in the...
