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?

Crash Damage ($)
Goliath	Varmint	Weasel
1,660	1,250	1,070
760	1,440	2,140
860	1,330	1,800
1,940	1,870	1,220
1,210	990	1,960

Based on the given hypotheses, choose the right option. H₀: ₁ = ₂ = ₃ H₁: Not all the means are equal = .05

multiple choice 2

• 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.

multiple choice 4

• False

• True

Based on the given hypotheses, choose the right option. H0: 21 = 22 = 23 H1: Not all the variances are equal = .0

multiple choice 6

• Reject the null hypothesis if H < 15.5

• Reject the null hypothesis if H > 15.5

Calculate the value of H_calc. (Round your answer to 2 decimal places.) H_calc On the basis of the above-determined H_calc, we reject the null hypothesis.

multiple choice 8

• False

• True
