I wonder how the two of you came to the conclusion of statistical
insignificance, and how you explain the apparent discrepancy of this
result with, say, the section titled "Estimating proportions and means"
on http://en.wikipedia.org/wiki/Sample_size_determination. [1]

I trust the audience would be delighted if you gave some insight
into the calculation.


[1] That link is admittedly a random pick, but Wikipedia seems to
be an acceptable replacement for lecture notes nowadays.
