Query: What is the true dropped calls rate when in the test it was found to be
  zero?   We study the distributions of dropped calls rates for different wireless
(cellular) carriers in different markets. Our statistics comprises over 700
different market/carrier combinations. We find that the dropped calls rates
distribution is very close to lognormal. We derive an equation for the most
probable dropped calls rate for particular carrier in particular market, which
depends on the number of dropped calls observed, total number of calls and the
parameters of the lognormal distribution. We apply this analysis to blocked and
"no service" calls as well.
