What is the

χ² _calculated value for the following situation.

• 6.65

• 6.66

• 0.00991

• 1

If the χ² _critical value = 5.991 and the

χ² test statistic = 7.352, what is the conclusion?

• Reject Ho, accept H1

• Accept Ho, reject H1

• There is not enough information to decide.

• The conclusion can only be made if we also know the p-value.

What are the degrees of freedom for the following χ² test?

• 6

• 2

• 5

• 12

If we are testing at a 5% significance level and our p-value is 0.00453, what is the conclusion?

• Accept Ho

• Reject Ho

• We need to know chi-squared

• You cannot do this problem without a calculator
