Based on the given hypotheses, choose the correct option

H<₀:₁=₂=₃

H₁: Not all the means are equal

= .05

multiple choice 1

• Reject the null hypothesis ifp-value < 0.05
• Reject the null hypothesis ifp-value > 0.05

On the basis of the above findings, we cannot reject the null hypothesis.

False

Based on the given hypotheses, choose the correct option.

H₀:²₁=²₂=²₃

H₁: Not all the variances are equal

= .05

Reject the null hypothesis ifH< 8.38

Calculate the value ofH_calc.(Round your answer to 2 decimal places.)

H_calc

On the basis of the above-determinedH_calc, we fail to reject the null hypotheses.

FALSE
