Need help

Here is the problem:

A researcher studying motivation asks subjects to search through a newspaper for the word
discipline. The researcher records how long (in minutes) each subject works at the task before finding the
word or giving up. For a sample of n = 20 people, the mean time was 29 minutes, the median was 17 minutes,
and the mode was 15 minutes.

If you rank ordered all the data, what's the maximum number of minutes that someone in the slower
half worked before finding a word or giving up?

no sure how to figure this out.

Review the definitions of "mean", "median", and "mode".... :wink:

I know that mean is the average, Mode is the number that occurs most frequently and the median is the middle value when all of the values are put into order. That being said, I know that the minumum amount of time that someone in the slower group would be 17 minutes, but I do not know how you can determine maximum time other than it would be more than 29 minutes.

How are you getting that the median is the lower limit on the lower half of the data...? :shock:
