Two types of football helmets, padded and suspension were compared to determine which had the lowest rate of impact damage. Forty helmets of each type were randomly selected and subjected to an impact test. The damage rates were 0.14 for padded and 0.45 for suspension. A 95% confidence interval estimate for the difference in the damage rates of the two types of helmets (padded minus suspension) is (-0.498. -0.122). After noticing that "0" is not included in the interval given and that both numbers are negative, what can you conclude what about the damage rates between the types of helmets? Be very specific and address context.
