People at SpaceX Inc conducted a pilot study
to determine the relationship between the
weight and cost of a major object being sent
into space. The results of the pilot study are
contained in data file ASP.1, available in the
LBRT #2 folder. Determine the number of
observations needed to be 89% confident
that the estimate of the average cost is within
$15 of the overall mean cost. Note: Assume
that the pilot study standard deviation is a
good estimate of the population standard
deviation, that an appropriate value from the
Z-table can be used, and that hand
calculations are used to find the answer (i.e.
do not use Kaddstat).
