Given the following 95% confidence interval on the acid rain example discussed in class, if someone made the claim that the mean pH level was 4.518, what would your statement be regarding his claim and why? Variable n Sample Mean Std. Err. pH_level 90 L. Limit U. Limit 4.577889 not given 4.5181427 4.6376348 O Based on the large sample size in this problem, the CLT supports your statement. O Your claim is not supported by my sample information, because it doesn't fall within the limits of my confidence interval. O If we follow this procedure many times, we would expect our Cl to contain the true population parameter about 95% of the time. O I cannot support or reject your claim, as I don't have an indication of the shape of the parent population. O Since the standard error is not given, the CI boundaries listed cannot be correct.
