Recall in our discussion of the binomial distribution the research study that examined schoolchildren developing nausea and vomiting following holiday parties. The intent of this study was to calculate probabilities corresponding to a specified number of children becoming sick out of a given sample size. Recall also that the probability, i.e. the binomial parameter "p" defined as the probability of "success" for any individual, of a randomly selected schoolchild becoming sick was given. Suppose you are now in a different...

A random sample of elementary school children in New York state is to be selected to estimate the proportion ?p who have received a medical examination during the past year. An interval estimate of the proportion p with a margin of error of 0.035 and 99% confidence is required. (a) Assuming no prior information about p^ is available, approximately how large of a sample size is needed? n= b) If a planning study indicates that p^ is around 0.70.7, approximately how large...

Imagine that you are doing an exhaustive study on the children in all of the elementary schools in your school district. You are particularly interested in how much time children spend doing active play on weekends. You find that for this population of 2,431 children, the average number of minutes spent doing active play on weekends is μ = 87.85, with a standard deviation of ơ-118.1. You select a random sample of 25 children of elementary school age in this...

3) Suppose you are an educational researcher who wishes to examine the effect of a school district's class size on its student achievement. Specifically, you are interested in whether in the U.S., on average, school districts with smaller class sizes perform differently on test scores than school districts with larger class sizes. To test this, you have conducted two surveys. The first survey randomly sampled 238 school districts with small class sizes. This survey found a sample average test score...

1. Approximately 30% of obese patients develop diabetes (p=0.3). If a physician sees 10 patients (n=10) who are obese, what is the probability that half of them will develop diabetes (Pr X=5)? [Hint: use the binomial equation] A. 0.10 B. None are correct C. 249.8 D. 3.34 * 10-6 E. 0.01 2. Obesity is a growing problem in the U.S. and educators are looking to determine the probability of children in their schools becoming obese...
