    A typical college student spends an average of 2.55 hours a day using a computer. A sample of 13 students at The University if Findlay revealed the following number of hours per day using the computer:

    3.15 3.25 2.00 2.50 2.65 2.75 2.35 2.85 2.95 2.45 1.95 2.35 3.75

    Can we conclude that the mean nunmber of hours per day using the computer by students at The University of Findlay is the same as the typical student's usage? Use the hypothesis testing procedure and the 0.05 significance level.

    Please resolve and explain this problem and show me the formula to do so.
