Chi-squared Hyp Testing

In a right tailed test, if the χ² _critical value = 25.99 and the

χ² _calculated value = 27.35, what is the conclusion?

• Reject H₀, accept H_a

• Accept H₀, reject H_a

• there is not enough info to decide

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

How do you find degrees of freedom for a chi-square test?

• one less than the sample size

• one less than the population

• total number divided 2

• total number times 2

• 38.885

• 15.379

• 13.844

• 41.923
