Question

You are trying to determine if a certain die is fair (has a uniform distribution). You roll the die 96 times and record the outcomes.

You conduct a chi-square Goodness-of-Fit hypothesis test at the 1% significance level.

(a)  The null and alternative hypotheses are:

  • H0: The die has the uniform distribution.
  • Ha: The die does not have the uniform distribution.

(b)  χ20=21.750.

 

(c)  Determine the critical value using the following portion of the χ2-table.

df χ20.10 χ20.05 χ20.025 χ20.01 χ20.005
