Tangpricha et al. did a study to determine whether fortifying orange juice with Vitamin D would result in change in the blood levels of five biochemical variables. In the experiment, 14 subjects drank 240 ml per day of orange juice fortified with 1000 IU of Vitamin D and 12 subjects drank 240 ml per day of unfortified orange juice. The following data, based on the results of the study, provides the decrease (negative values indicate increase) in PTH levels, in pg/mL, for those drinking the fortified juice and for those drinking the unfortified juice.

9. Auto Exhaust and Lead Exposure Researchers interested in lead exposure due to car exhaust sampled the blood of 19 police officers subjected to constant inhalation of automobile exhaust fumes while working traffic enforcement in a primarily urban environment. The blood samples of these officers had an average lead concentration of 11.2µg/dl and a SD of 4.5µg/dl; a previous study of individuals from a nearby suburb, with no history of exposure, found an average blood level concentration of 7.2μg/dl. (a) Test the hypothesis that the downtown police officers have a higher lead exposure than the officers in the previous study. Be sure to interpret your results in context. a = = 0.05 (b) Explicitly state and check all conditions necessary for inference on this data. (c) Based on your preceding result, without performing a calculation, would a 90% confidence interval for this difference contain 0? Explain why or why not.
23.2 Aerosolized Vaccine for Measles. An aerosolized vaccine for measles wwas (pages 530 and 532). process developed in Mexico and has been used on more than 4 million children since 1980, Aerosolized vaccines have the advantages of being able to be administered by people without clinical training and do not cause injection-associated infec tions. Despite these advantages, data about efficacy of the aerosolized vaccines against measles compared to subcutaneously injection of the vaccine have been inconsistent. Because of this, a large randomized controlled study was conducted using children in India. The primary outcome was an immune response to measles measured 91 days after the treatments. Among the 785 children receiving the sub- cutaneous injection, 743 developed an immune response, while among the 775 children receiving the aerosolized vaccine, 662 developed an immune response. (a) Compute the proportion of subjects experiencing the primary outcome for both the aerosol and…

Answer the following:
It has been hypothesized that allergies result from a lack of early childhood exposure to antigens. If this hypothesis were true, then we would expect allergies to be more common in very hygienic households with low levels of bacteria and other infectious agents. To test this theory, researchers at the University of Colorado sampled the houses of 61 children 9-24 months old and recorded two variables: (1) whether the child tested positive for allergies and (2) the concentration of bacterial endotoxin in the house dust (endotoxin units per ml, EU/ml)1. The following are the endotoxin levels at the homes of the 51 children tested negative for allergies. 708.23 911.60 976.81 1316.63 262.74 9772.08 370.76 229.16 2570.51891.19 3163.20 1777.65 1288.57 436.23 2631.63 1173.52 911.67 7942.42 740.32 356.92 1175.48 1480.55 2754.61 575.62 573.89 468.26 1000.71 364.22 1025.26 1022.04 645.41 363.57 977.47 1022.75 1860.63 371.13 174.73 399.68 1479.77 2882.96…
An experiment to evaluate the effectiveness of the type of snack and children's perception of satiation was designed so that subjects aged 10 to 13 years were randomly assigned a snack that was of the exact same ingredients but described differently. The first group had their snack described as healthy and full of vitamins, the second group had their snack described as tasty, the third group were given a snack without any description whatsoever. Thirty minutes after finishing the snack, subjects were asked to rate their hunger on a scale of 1 to 10. The results are summarized in the table: ANOVA: Single Factor SUMMARY Groups Healthy Tasty No Description ANOVA Source of Variation Between Groups Within Groups Total Count 12 13. 14 SS 17.46154 62.89744 80.35897 Sum 62 46 56 Average 5.1667 3.5385 4.0000 Variance 1.9697 1.9359 1.3846 df MS F P-value 2 8.730769 4.997146 0.012156 36 1.747151 38 Based on these results, at a 5% level of significance what conclusion can the researchers draw from…
