Question 1:

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 ug/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 video which as of this writing has had over 30 million views online. The date 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 200 400 600 Concentration (negg cr) 15 Concentration (neglig cr) Concentration (negg er) Concentration (ncgg cr) 5 Non-Organic Organic Non-Organic Organic Non-Organic Organic Non Organic Organic ETU Mepiquat Propamocarb TCP 120 15 10 Concentration (mogg art) Concentration (mogg art) Concentration (mogg ort) Concentration (mogg ort) 50 Non-Organic Organic Non-Organic Organic Non-Organic Organic Non-Organic Organic Figure 1Eating 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. i . . . . 15 20 25 30 35 24.518 Figure 2 Click here for the dataset associated with this question.

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 then 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. e Textbook and Media (f) Does this interval provide evidence that concentrations of the pesticide 3-PBA are lower while eating organic?
