The Organic Effect This Exercise pertains to a 2015 study" which took a Swedish family that ate a conventional diet (non-organic), and then had them eat only organic for two weeks. Pesticide concentrations for several different pesticides were measured in up/g creatinine by testing morning urine. Multiple measurements" were taken for each person before the switch to organic foods, and then again after participants had been eating organic for at least one week. The results are pretty compelling, and are summarized in a short videos which as of this writing has had over 30 million views online. The data are visualized in Figure 1 for eight different detected pesticides, and can be found in OrganicEffect. How do pesticide levels in the body differ after eating organic versus non-organic? 240 3-PBA 35DC CCC 40 60 200 403 6 Concentration [mogg ert) Concentration (mogg ert) Concentration (megig er) Concentration (mogg er) 1III 20 5 Non-Organic Organic Non-Organic Organic Non-Organic Organic Non-Organic Organic ETU Mepiquat Propamocarb TCP 120 150 80 10 Concentration (mogig ert) Concentration (mogig crt) Concentration imogig crt) Concentration (mogig crt) 40 50 Non-Organic Organic Non-Organic Organic Non-Organic Organic Non-Organic Organic Figure 1 Eating Organic and 3-PBA Levels We first study 3-PBA, a commonly used insecticide found in grains, fruits, and vegetables. How much higher are 3-PBA concentrations while not eating organic versus eating organic? A bootstrap distribution based on 1000 samples of the mean concentration before the switch minus the mean concentration after switching to organic is shown in Figure 2.We first study 3-PBA, a commonly used insecticide found in grains, fruits, and vegetables.

For illustrative purposes we will assume the measurements were far enough apart to be unrelated.

": P2 HI - eTextbook and Media(c) Use the bootstrap distribution to estimate the sample statistic. Round your answer to one decimal place. Sample statistic i 0.3 eTextbook and Media (d) Use the bootstrap distribution to estimate a 99% confidence interval. Round your answers to the nearest integer. The interval is i HE/g crt to i HE/g crt. e Textbook and Media (e) Interpret this interval in context. O We are 99% confident that the people in the sample had 3-PBA concentrations between 15 and 35 units higher when eating non-organic than when eating organic. O Between 15% and 35% of people have higher concentrations of 3-PBA when eating non-organic than when eating organic. O We are confident that 99% of people have 3-PBA concentrations between 15 and 35 units higher when eating non- organic than when eating organic. O We are 99% confident that the people in the sample had mean 3-PBA concentrations between 15 and 35 units higher when eating non-organic than when eating organic. O We are 99% confident that all people will have mean 3-PBA concentrations between 15 and 35 units higher when eating non-organic than when eating organic. eTextbook and Media(f) Does this interval provide evidence that concentrations of the pesticide 3-PBA are lower while eating organic? eTextbook and Media (g) Can we conclude that eating organic causes lower concentrations of 3-PBA? eTextbook and Media
