Question

Is Fast Food Messing With Your Hormones? Examine the results of a study investigating whether fast food consumption increases one's concentration of phthalates, an ingredient in plastics which has been linked to multiple health problems including hormone disruption. The study included 8877 people who recorded all the food they ate over a 24-hour period and then provided a urine sample. Two specific phthalate byproducts were measured (in ng/mL) in the urine: DEHP and DiNP. Find a 99% confidence interval for the difference, ?_F ? ?_N, in mean concentration between people who have eaten fast food in the last 24 hours and those who haven't. The mean concentration of DiNP in the 3095 participants who had eaten fast food was x?_F = 10.1 with s_F = 38.9 while the mean for the 5782 participants who had not eaten fast food was x?_N = 7.0 with s_N = 22.8. Round your answers to two decimal places. The 99% confidence interval is [ ] to [ ].
