Many of the environmental statutes permit citizen suits. As a result, environmental groups bring many lawsuits against both the EPA and polluters, alleging violations of these statutes. Are these suits a good idea? The Fish and Wildlife Service says that it spends so much of its resources responding to litigation over why it has not listed endangered species that it has no resources left to actually to do the listing. Businesses argue that it is unfair for every citizen to...

The life in hours of a 75-watt light bulb is known to be approximately normally distributed, with standard deviation σ = 25 hours. A random sample of 62 bulbs has a mean life of x-bar = 1,014 hours. Construct a 98% confidence interval around the true population mean life of the light bulb.

Suppose a drug is known to have mild side effects in 75% of the people who take it . It is administered to 100 people. Using both the binomial distribution and the normal approximation, you have calculated the probability that more than 70 people will experience mild side effects. Based on your answers to the previous questions, choose all that apply. i. Since our experimental conditions satisfy the requirements for its use, the estimate from the normal approximation is appropriate...

Duplication of genes is an important evolutionary mechanism. As a result, many, cases are known in which a species has two or more identical genes. Suppose there are two genes - A and B - that specify production of the same enzyme. These two genes show autosomal recessive inheritance. An abnormal phenotype results only if an individual does not make any of that enzyme. Only one of these two genes needs to be functional in order to make the enzyme....

In an environmental project, a ground source heat pump system will be installed, which will result in an annual fuel savings of 2000 HK$/year. The initial investment of the heat pump system is 14 000 HK$. The life-time of the heat pump system is 20 years. The annual maintenance cost is 300 HK$/year. At the end of the 20 years' life time, the salvage value is 1500 HK$. The interest rate is 10%. (1) What is the net present value...
