MO21. The brightness of a television picture tube can be evaluated by measuring the amount of current required to achieve a particular brightness level. The following data (required current) were collected from a sample: 343.8, 369.3, 380.6, 339, 369.7. Compute a 90% confidence interval on the brightness of the television tubes that has 90% of the values. Input the value the upper limit of the Tolerance Interval in the blank provided up to 2 decimal places. Provide all the necessary solutions in the submission for both upper and lower limit.
