Question

Suppose that the mean time for a certain car to go from 0 to 60 miles per hour was 8.8 seconds. Suppose that you want to set up a statistical test to challenge the claim of 8.8 seconds. What would you use for the null hypothesis? A)H₀ : $\mu$$\gt$ 8.8 seconds B)H₀ : $\mu$= 8.8 seconds C)H₀ : $\mu$< 8.8 seconds D)H₀ : $\mu$$\neq$8.8 seconds E)H₀ : $\mu$$\le$8.8 seconds

Quizplus · Accepted Answer

The null hypothesis in statistical tests typically assumes no effect or no difference, meaning it would state that the mean time is equal to the claimed time of 8.8 seconds.
