The most commonly accepted tradition is that undergraduate college students will study 2 hours outside of class for every hour in class. This means 30 hours/week for a full-time student taking 15 units (hours of class). An educator suspects that this figure is different now than in the past.

  • Claim 1: The average time full-time undergraduate college students study outside of class per week is 30 hours.
  • Claim 2: The average time full-time undergraduate college students study outside of class per week is not 30 hours.

To substantiate her claim, the educator randomly selects 1,500 college students and finds that they study an average of 27 hours per week with a standard deviation of 1.7 hours.
