D Question 8 0.5 pts A study was performed to estimate the prevalence of peanut allergies in Washoe County elementary school children. Ten elementary schools were randomly chosen to participate in the study. Allergy status was determined using a peanut allergy IgE test. To be allowed to participate in the study, each child had to obtain parental permission. The scientists noted that student participation was high at elementary schools located in affluent neighborhoods. Study participation was lower at elementary schools located in less affluent neighborhoods. The scientists did a literature review, and they found that socioeconomic status is not a risk factor for peanut allergy The under-representation of students from elementary schools located in less affluent neighborhoods introduced which type of error? No error is introduced by this Selection bias Information bias (misclassification) Random error from sampling
