Suppose that the quarterly sales levels among health care
information systems companies are approximately normally
distributed with a mean of 12 million dollars and a standard
deviation of 1.1 million dollars. One health care information
systems company considers a quarter a "failure" if its sales level
that quarter is in the bottom 20% of all quarterly sales levels.
Determine the sales level (in millions of dollars) that is the
cutoff between quarters that are considered "failures" by that
company and quarters that are not. Carry your intermediate
computations to at least four decimal places. Round your
answer to one decimal place.
