A sample of \(n=25\) children is selected, and a survey is sent to each child's parents. The results indicate an average of \(M=3.1\) hours per day with a standard deviation of \(s=3.0\)

  1. Make a point estimate of the mean number of hours of TV per day for the population of elementary school children
  2. Make an interval estimate of the mean so that you are \(90 \%\) confident that the true mean is in you interval.
