12 different video games showing substance abuse were observed and the duration of times of gameplay, 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 the standard deviation times of gameplay.  Assume that this sample was obtained from a population with a normal distribution. 4,404   4,715    4,567   4,758    4,427   5031 3,984   3,925   3,971    4,766    4281    4,845
