In a recent study, the Centers for Disease Control and Prevention reported that in a sample of 4,349 African Americans 31% were Vitamin D deficient. Overall, it is believed that Vitamin D deficiency affects 8% of all U.S. adults.Test, at the 1% significance level, if this sample provides evidence that the rate of Vitamin D deficiency among African Americans differs significantly from the overall rate of 8%. Include all of the details of the test.

A disruption of a gene called DYXC1 on chromosome 15 for humans may be related to an increased risk of developing dyslexia. Researchers1 studied the gene in 109 people diagnosed with dyslexia and in a control group of 195 others who had no learning disorder. The DYXC1 break occurred in 10 of those with dyslexia and in 5 of those in the control group.  1Science News, August 30, 2003, p 131.(a)    Is this an experiment or an observational study?   __________(b) How many rows and how many columns will the data table have? Assume rows are the cases and columns are the variables. (There might be an extra column for identification purposes; do not count this column in your total.)Number of rows: __________Number of columns: _____________(c) Display the results of the study in a two-way table.     Gene break No break Total   Dyslexia group   Control group   Total  (d) To see if there appears to be a substantial difference between the group with dyslexia and the control group, compare the proportion of each group who have the break on the DYXC1 gene. Round your answers to three decimal places.Proportion for dyslexia group: ____________Proportion for control group: ______________(e) Does there appear to be an association between this genetic marker and dyslexia for the people in this sample?  Yes or No(f) If the association appears to be strong, can we assume that the gene disruption causes dyslexia?  Yes or No

Plastic microparticles are contaminating the world’s shorelines, and much of this pollution appears to come from fibers from washing polyester clothes.1 The worst offender appears to be fleece, and a recent study found that the mean number of polyester fibers discharged into wastewater from washing fleece was 290 fibers per liter of wastewater, with a standard deviation of 87.6 and a sample size of 120. 1Browne, M., et. al., ‘‘Accumulation of Microplastic on Shorelines Worldwide: Sources and Sinks,” Environmental Science and Technology, 2011; 45: 9175-9179. Data are approximated from information given.(a) Find a 95% confidence interval for the mean number of polyester microfibers per liter of wastewater when washing fleece. Round your answers to one decimal place. ___________ to ____________(b( What is the margin of error? Round your answer to one decimal place. ____________(c) If we want a margin of error of only ±7 with 95% confidence, what sample size is needed?Round your answer up to the nearest integer.    sample size = _________

Is citizen engagement worth the effort? Why would governments choose to engage with citizens? What are the risks of citizen engagement? Make sure to discuss both process and outcomes. What are some of the different ways that governments engage their citizens- name at least two? How do these forms of engagement work? Are there specific circumstances in which citizen engagement is more or less likely to succeed? You must reference the class material.
