{Time Spent Playing Computer Games Narrative} Determine and interpret the 90% confidence interval estimate of the population mean.
Standard Deviation
Standard deviation is a measure of the amount of variation or dispersion of a set of values, indicating how much the values in a data set differ from the mean of the data set.
Confidence Interval
A statistical measure that provides an estimated range of values likely to include a population parameter, calculated from a given set of sample data.
Population Mean
The population mean is the average value of all data points in a full set of values, representing the central tendency of the population.
- Gauge the confidence intervals for the population mean, with an eye towards differing confidence levels, sample sizes, and population standard deviations.
- Discern the implications that results from confidence intervals have on population parameters.

Final Answer :
LCL = 6.25 and UCL = 6.75 (hours per week).Repeated samples correctly estimate this average 90% of the time.
