Acid rain A study of the effects of acid rain on trees in a certain forest shows that 46 of 150 trees sampled exhibited some sort of damage from acid rain. This rate seemed to be higher than the 17% quoted in an ecosystem study report on the average proportion of damaged trees in the region. Does the sample suggest that trees in the given forest are more susceptible than trees in the rest of the region?
