A study of the effects of acid rain on trees in a particular forest shows that 32 of 110 trees sampled exhibited some sort of damage from acid rain. This rate seemed to be higher than the 18% quoted in a recent article on the average proportion of damaged trees in the Northeast. Does the sample suggest that trees in this forest are more susceptible than trees from the rest of the region? Comment, and write up your own conclusions based on an appropriate confidence interval as well as a hypothesis test. Include any assumptions you made about the data. A. The 10% condition is met. B. The randomization condition is met. C. The success/failure condition is met. D. The independence assumption is met. E. None of the assumptions and conditions are met. Determine the test statistic. 3.03 (Type an integer or decimal rounded to two decimal places as needed.) Determine the P-value. P-value = .001 (Type an integer or decimal rounded to three decimal places as needed.) State your conclusion. Consider a P-value smaller than 0.05 to be low. The 95% confidence interval is (0.280. 0.302). The P-value is low so we reject the null hypothesis. There is strong evidence that the proportion of trees damaged by acid rain in this forest is higher than the 18% average for the Northeast. (Type integers or decimals rounded to three decimal places as needed.)
