Question

A die is rolled 120 times to see if it is fair. The table below shows the frequencies for each of the six possible outcomes.  Use a level of significance of αα = 0.05.

  1. Complete the rest of the table by filling in the expected frequencies (enter your answers in fraction form):
    Frequency of Dice Values
    Outcome Frequency Expected Frequency
    1 18

     

    2 17  
    3 25  
    4 15  
    5 26  
    6 19  
  2. What is the correct statistical test to use?
         
  3. What are the null and alternative hypotheses?
    H0:H0: 
    • The distribution of die rolls is uniform.
    • The die rolls are dependent.
    • The die rolls are independent.
    • The distribution of die rolls is not uniform.



    H1:H1: 
    • The die rolls are dependent.
    • The distribution of die rolls is uniform.
    • The die rolls are independent.
    • The distribution of die rolls is not uniform.
  4. The degrees of freedom = 

  5. The test-statistic for this data =  (Please show your answer to three decimal places.)

  6. The p-value for this sample = (Please show your answer to four decimal places.) 

  7. The p-value is     αα 

  8. Based on this, we should     
  9. Thus, the final conclusion is...
    • There is sufficient evidence to conclude that the distribution of die rolls is not uniform.
    • There is sufficient evidence to conclude that the die rolls are dependent.
    • There is sufficient evidence to conclude that the distribution of die rolls is uniform.
    • There is insufficient evidence to conclude that the die rolls are dependent.
    • There is insufficient evidence to conclude that the distribution of die rolls is not uniform.
