Question

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 95​% confidence interval estimate of sigma​, the standard deviation of the duration times of game play. Assume that this sample was obtained from a population with a normal distribution. 4 comma 980 3 comma 995 3 comma 894 3 comma 989 4 comma 162    4 comma 891 5 comma 025 4 comma 736 4 comma 797 3 comma 970 4 comma 174 4 comma 082 LOADING...
