Twelve different video games showing substance use were observed
and the duration of times of game play (in seconds) are
listed below. The design of the study justifies the assumption that
the sample can be treated as a simple random sample. Use the sample
data to construct a 99% confidence interval estimate of σ, the
standard deviation of the duration times of game play. Assume that
this sample was obtained from a population with a normal
distribution.
