In Dallas, some fire trucks were painted yellow (instead of red) to heighten their visibility. During a test period, the fleet of red fire trucks made 153,348 runs and had 20 accidents, while the fleet of yellow fire trucks made 135,035 runs and had 4 accidents. At α = .01, did the yellow fire trucks have a significantly lower accident rate?

(a) State the hypotheses.

(b) State the decision rule and sketch it.

(d) Make a decision.

(e) Find the p-value and interpret it.

(f ) If statistically significant, do you think the difference is large enough to be important? If so, to whom, and why?

(g) Is the normality assumption fulfilled? Explain.
