Johny, trying to reduce, followed a certain diet
during the month of April.
He recorded his weight daily at 8:00, naked
, using the same balance.
Some of his entries are given below:
Apr 3...........102.6 kg
Apr 8...........101.1 kg
Apr 14.........99.4 kg
Apr 18.........98.7 kg
Apr 22.........98.0 kg
Apr 28..........97.6 kg
Please provide your estimate of his average April weight.
I am very busy, packing my staff for 11 days vacation (Ibiza, Rome & Napoli)- I will need some time to post my opinion, - solving my own puzzle should be given due consideration. Later!
However, 2 remarks pop up immediately upon seeing the 4 posts:
1. How can one justify 96.3 as an average while such value is lower than each of the weights mentioned? I wonder.
2. Let us not worry about the fluctuations during the day-we should standardize the question: What is your estimate of the average of his 8:00 weight samples in April (i.e.during 30 days) .
IMHO the different methods should not produce answers as diverging as those given so far.
