Greetings!
The following from my local branch of the BBC:

"Jigsaw puzzle test for Royal Mail
A post office watchdog is testing performance across
the region by sending out jigsaws to charities.
Postwatch East of England is sending out a 30-piece
jigsaw over four days to nine charities in each of the
different postcode areas in the region.
The first to receive all the puzzle pieces will win
a cash prize.
"We wanted to test postal deliveries across the region
and felt this was a fun way to do so," said Postwatch
chairman Dr Charles Winstanley.
He said that postcode areas in the UK have a next day
delivery target of 91%.
"We are excited to see which area performs the best and
will be waiting for the call from the winning charity,"
Dr Winstanley added.
All charities will receive a donation for taking part.
Postwatch will begin to send out pieces of the jigsaw to
charities from 4 July and the final pieces will be posted
on 7 July."
(Found on the BBC Cambridgeshire website).
I surmise from the above that 30 packets, each with 1 piece
of the jigsaw, will be sent to each of 9 charities over 4 days
(or maybe 4 packets, each with some of the pieces, on each
of 4 days).
Anyway, I'm intrigued by the question: What is the power of
this survey design to detect failure to meet the 91% next-day
delivery target?
Puzzle for you.
Best wishes to all,
Ted.
