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 ​95% confidence interval estimate of o ​, the standard deviation of the duration times of game play. Assume that this sample was obtained from a population with a normal distribution. 4316
