PLEASE HELP!!! Twelve different video games showing substance use were observed and the duration 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 data to construct a 90% confidence interval estimate of µ, the mean duration of game play. 4049 3881 3854 4030 4324 4816 4661 4040 5001 4821 4327 4326 What is the confidence interval estimate of the population mean µ ? __ < µ < __ (round to one decimal place as needed)
