• Data: Ages of patients at two clinics.

  • Question: Do the two clinics differ in terms of the distribution of ages of their patients?

  • Analysis:

    Two Sample T-Test and Confidence Interval

    Two sample T for Age

    95%CI for mu (1) - mu (2): ( -4.05, 0.05)
    T-Test mu (1) = mu (2): T = -1.94 P = 0.056 DF = 78
    Both use Pooled StDev = 4.61
