More about lost sleep

sleep1

Following the earlier study,  our client has now produced some further data covering three weeks’ holiday, with results as shown above.  We suspect that the slightly anomalous results for Sunday are indeed due to there only being three observations.  The mean amount of sleep per night is 6:32 for the Work period and 7:08 for the Holiday period.

So there is some difference, but hardly enough to say that the client is compelled to give up work.  He will have to make his own decision, which is rarely a popular piece of advice…
