In the Marist Institute allergy survey, 2.5% of a national wide randomly selected sample of n = 880 suffer from severe allergies. A researcher suspects that the true proportion is higher than 10%. Let p denote the true proportion of people that suffer from severe allergies. Based on a 95% CI for p, either the null hypothesis or the alternative hypothesis (as determined by researcher's claim) is likely (or unlikely) to be true. Suppose new information on the population yields the true proportion of people suffering from severe allergies is actually 18.5%. When comparing the conclusion from the 95% CI for p to the newly available information about the true p, what type of error (if any) has occurred? the decision/conclusion is not in error. Type I error has occurred. Type II error has occurred. no assessment can be made because normality is not given.
