Manufacturers are testing a die to make sure that it is fair (has a uniform distribution). They roll the die 100 times and record the outcomes. They conduct a chi-square Goodness-of-Fit hypothesis test at the 1% significance level. The null and alternative hypotheses are: H0: The die has the uniform distribution. Ha: The die does not have the uniform distribution. The test statistic for the data is χ20=28.165. The critical value is χ20.01=15.086. What conclusions can be made? Select all that apply. Select all that apply: We should reject H0. We should not reject H0. At the 1% significance level, there is sufficient evidence to conclude that the die is not fair. At the 1% significance level, there is not enough evidence to conclude that the die is not fair.
