    Step-by-step explanation:

    Enter data into L₁

    CL = 0.95

    df = 3

    Distribution: xbar ~ t₃

    Calculator commands (for TI only) : [Stat],[TESTS],[TInterval],[Data], (List: L₁), (Freq:1), (C-Level:0.95),[Calculate]

    Confidence interval (20.532,21.468)

    We can conclude that the true population mean for bags of potatoes labeled 20.0 pounds is between (20.532,21,468) with a 95% confidence level.
