Assume that eighteen samples are drawn from Lake Ontario. Each sample of water has a 10% chance of containing a particular pollutant. Assume that the samples are independent with regard to the presence of pollutant.

(a) What is the probability that exactly two do not contain the pollutant?

An environmental engineer working for the EPA is tasked with observing water specimens from lakes in northeast Georgia. In this region, each water specimen has a 10 percent chance of containing a particular organic pollutant. (a) Treating each water specimen as a “trial,” suppose the three Bernoulli trial assumptions hold. State what this would imply (i.e., just give the assumptions for this situation). (b) Let Y denote the number of specimens that contain the pollutant out of the next 15...

5) A concrete plant takes 20 independent samples of concrete each month. The samples are cured and strength tested to evaluate quality control at the plant. Let N20 be the number of samples which fall below a strength of 20 MPa. In general the fraction of such low strength samples is around 10%, and this is considered acceptable. However, if the samples taken in a particular month yield a value of N20 which exceeds its mean by more than two...

Choose a quantitative variable. Measure it on two different samples of 10, drawn from two different populations. For example, you might measure the number of cups of chocolate consumed daily by men vs women. Provide a description of the data selected, and the two different populations you chose. Record the data, and for EACH sample, find the mean and standard deviation and the five-number summary. Compare your two samples using boxplots or histograms. Summarize your results in a paragraph, including...

A small town gets its water supply from three nearby lakes, A, B, and C. Sometimes in the late summer the water level in a lake falls below a certain critical level. When this occurs, there is a risk that the water from that lake will become polluted with E-Coli. If the water supply to the town becomes polluted, the residents are advised to boil their water. If only the water level at lake A falls below the critical level,...

Assume we have a box with 10 chips, each with a number written on it from 1-10. We reach in, pull out a chip, look at the number and write it down, then put the chip back. We do this 2 times. We describe this as N = 2 for the sample size. Then we take the mean of the two numbers we recorded. We repeat this 5000 times, each time drawing a random sample of 2, with replacement (i.e.,...

Water samples are taken from water used for cooling as it is being discharged from a power plant into a river. It has been determined that as long as the mean temperature of the discharged water is at most 150 degrees Fahrenheit, there will be no negative effects on the river ecosystem. To investigate whether the power plant is in compliance with regulations that prohibit a mean discharge water temperature above 150 degrees, a scientist will take 50 water samples...
