More than a decade ago, high levels of lead in the blood put 81% of children at risk. A concerted effort was made to remove lead from the enviornment. Now suppose only 17% of children in the United States are at risk of high blood- level leads. A. In a random sample of 186 children taken more than a decade ago, what is the probability that 50 or more had high blood levels? B. In a random sample of 186...

In the following problem, check that it is appropriate to use the normal approximation to the binomial. Then use the normal distribution to estimate the requested probabilities. More than a decade ago, high levels of lead in the blood put 83% of children at risk. A concerted effort was made to remove lead from the environment. Now, suppose only 11% of children in the United States are at risk of high blood-lead levels. (a) In a random sample of 212...

Iron-deficiency anemia is an important nutritional health problem in the United States. A dietary as- sessment was performed on 51 boys 9 to 11 years of age whose families were below the poverty level. The mean daily iron intake among these boys was found to be 12.50mg with standard deviation 4.75mg. Suppose the mean daily iron intake among a large population of 9 to 11 year-old boys from all income strata is 14.44 mg. We want to test whether the...

According to the Center for Disease Control (CDC), about 1 in 88 children in the United States have been diagnosed with autism. a. In your study, you are randomly selecting a group of 24 children from the population of school-aged children in your area. Your random variable is the number of children in your sample with autism. Explain why you can use the binomial probability distribution to determine the probabilities of possible number of children in your study having autism...

Question 1 O pts Problem 1: (21 points] Young children in the United States are exposed on an average of 4 hours of background television per day. Having the television on in the background while children are doing other activities may have adverse consequences on a child's well-being. You have a research hypothesis that children from low-income families are exposed to more thart 4 hours of daily background television. In order to test this hypothesis, you have collected data on...

Young children in the United States are exposed to an average of 4 hours of background television per day. Having the television on in the background while children are doing other activities may have adverse consequences on a child’s well-being. You have a research hypothesis that children from low-income families are exposed to more than 4 hours of daily background television. In order to test this hypothesis, you have collected a random sample of 64 children from low-income families and...

Compare the population health of the United States to any other country by answering the following questions: What do statistics/data tell us about health outcomes in general of each country? What specific diseases are endemic and have been epidemic? What inequalities are evident from your research? What resources are available to those with low incomes? What type of governmental assistance is available and to whom? How much of the countries' GDPs are allocated to health care services? What are some...
