A test was given to seven classes to assess student's knowledge of probability and statistics. The average test scores for each of the seven classes are listed below.

{ 76%, 61%, 82%, 84%, 75%, 80%, 79% }

Use these sample values to calculate a 90% confidence interval estimate of the average test score for these classes. Do this calculation by hand, showing the details of each step.
