Question

In a bumper test, three types of autos were deliberately crashed into a barrier at 5 mph, and the resulting damage (in dollars) was estimated. Five test vehicles of each type were crashed, with the results shown below. Research question: Are the mean crash damages the same for these three vehicles?

Based on the given hypotheses, choose the right option.
 
H
0μ1 = μ2 = μ3
H1: Not all the means are equal
 
α
 = .05
 

  • Reject the null hypothesis if p-value > 0.05
  • Reject the null hypothesis if p-value < 0.05

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

 
Based on the given hypotheses, choose the right option. H0: σ21 = σ22 = σ23 H1: Not all the variances are equal α = .0
 
  • Reject the null hypothesis if H < 15.5
  • Reject the null hypothesis if H > 15.5

 
Calculate the value of Hcalc(Round your answer to 2 decimal places.)
 
H
calc             
 
On the basis of the above-determined Hcalc, we reject the null hypothesis.
 
  • True
  • False
