tions both equal 10. The mean and median of
Bev's n = 5 observations both equal 18.
(a) Carol combines Al's and Bev's data into
one collection of n
8 observations.
Can the mean of Carol's data be calculated
from the information given? If you think
not, just say that. If you think it can, them
calculate Carol's mean.
(b) Refer to part (a). Demonstrate, by an ex-
plicit example, that there is not enough
information to determine Carol's median.
Hint: Find two sets of data sets that sat-
isfy Al's and Bev's conditions, yet, when
combined, give different medians.
