1)Investigators studied whether pesticide exposure was associated with developmental delay in kindergarten students. Researchers recruited 250 students with developmental delay (DD) and found a comparison group of neighborhood children. Of those with developmental delay, 37 had parents who reported high pesticide exposure in early infancy. Of the 500 children with normal development, 18 parents reported high pesticide exposure. Calculate the appropriate measure of association for this study.Which of the following is most likely to impact the results of the study above?Group of answer choicesEcologic fallacyLoss to follow-upNon-complianceMeasuring more than one etiological/exposure factorDifferential Recall2)Use the scenario below to answer the following 2 questions. Investigators were interested in the association between alcohol use and academic performance. They conducted a survey of 500 students at local university and asked them about whether they consumed alcohol since enrolling at the university (Exposure: Yes vs. No) and also to report their current GPA (Outcome: =3.00). Of the 145 with a GPA =3.00, 97 reported drinking alcohol. Complete the following 2×2 table for the study aboveBased on the 2×2 above, calculate and interpret the measure of association in this study.Students who consumed alcohol had 2.37 times higher odds of having a GPA <3.00 compared to those who did not drink alcohol.Students who consumed alcohol had 2.37 times higher prevalence of a GPA <3.00 compared to those who did not drink alcohol.Students with a GPA =3.00.Students who consumed alcohol had 3.56 times the risk of having a GPA 6419,303,1164,848,426Total deaths, All causes 2015Total>64131,45433,178New cases of cancer, 2015Total>6419,0624,227Deaths due to CVD, 2015Total>6424,54015,871Deaths due to Cancer, 2015Total>6421,0405,10What was the mortality rate among individuals older than age 64 in Florida in 2015?6.8 per1,000 Floridians older than 659.9 per 1,000 Floridians older than 6510.1 per 1,000 Floridians older than 659.9% of Floridians older than 65Which of the following can you calculate from the table above?CVD-specific morality rateProportionate mortality from CVDCase fatality from CVDBoth CVD-specific mortality rate and Proportionate mortality from CVDAll of these can be calculated
