Question 913820: 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 sample data to construct a 99% confidence interval estimate of u (mew) ((population mean)) the mean duration of game play. 4051 3891 3854 4026 4319 4823 4656 4039 5013 4828 4344 4311.
What is the confidence interval estimate of the population mean u? ____ Round to one decimal place as needed.

mean = 4346.3, sd = 397.2
99% confidence interval
ME = 397.2(2.576)/sqrt(12) = 295.4
CI: (4346.3 -ME , 4346.3 + ME)
