Twelve different video games showing substance use were observed and the duration of times of game playβ (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 an 80β% confidence interval estimate of Οβ, the standard deviation of the duration times of game play. Assume that this sample was obtained from a population with a normal distribution. The confidence interval estimate is:. 4,190 3,914 4,455 4,244 3,988 4,223 3,819 4,339 3,984 4,012 3,905 3,807
