A research study hypothesized that people who drive hybrid cars are less likely to smoke than people who drive minivans or SUVs (who do not differ from each other). In conducting a one-way ANOVA with this data, how could the null hypothesis (H₀) be stated? A) H₀: Hybrid

Question

A research study hypothesized that people who drive hybrid cars are less likely to smoke than people who drive minivans or SUVs (who do not differ from each other). In conducting a one-way ANOVA with this data, how could the null hypothesis (H₀) be stated? A) H₀: Hybrid < Minivan = SUV B) H₀: μHybrid = μMinivan = μSUV C) H₀: all μs are not equal D) H₀: Hybrid ≠ Minivan = SUV

The null hypothesis for a one-way ANOVA states that there is no difference in means between the groups being compared. In this case, the null hypothesis would be H₀: μHybrid = μMinivan = μSUV, meaning that the means for smoking rates among drivers of hybrid cars, minivans, and SUVs are all equal.
