Document Summary

Demography: the study of the characteristics of human populations ex. geographers study the distribution of population (spatial patterns) from international to local level. How places shape populations and how populations shape places. Family reconstruction: the process of reconstructing individual and family life his- tories by linking together separately, recorded birth, marriage, and death data. Quebec historians have been able to reconstruct the demographic ex- periences of entire communities, using the techniques of family recon- struction and have been able to provide a glimpse into life along the st. In many cases, it is necessary to utilize numerous other types of data to say something about a past populations size and structure. To get a full picture of what is happening population experts prefer to use a combination of both census and vital record information, censuses give us a far richer data picture.

The fish population P(t) in a lake is suddenly attacked by adisease that render the fish unable to reproduce. Assuming that thedeath rate of the fish is inversely proportional to the square rootof the fish population (i.e. k1 = Î²/â(P) where Î² is aconstant), perform the following tasks:

1. Write a differential equation that models the population offish as a function of time. Assume that the fish are infected bythe disease at t = 0 and define your constants.

2. Solve the differential equation with the initial condition thatP(0) = P0.

3. What is the half-life of the fish population?

4. If there were 900 fish initially, and 441 are left after 6weeks, how long does it take for all the fish to die? Assume thatthe disease was caused by radioactive waste dumped in the lake. Itis discovered that another population of fish, S(t), spontaneouslymutate into the original fish at a rate of k2 (per week) and neverdie. The population S(t) are born at a rate k3.

5. Draw a diagram that describes the life cycle of these twofish populations including your rate constants.

6. Write the differential equations describing the populationsof P(t) and S(t).

In February 2002, a total of 60.7 billion kW · h of electrical energy was generated by nuclear power plants in the United States. At that time, the population of the United States was about 287 million people. If the average American has a mass of 60 kg, and if 35.13% of the entire energy output of all nuclear power plants was diverted to supplying energy for a single giant elevator, estimate the height h to which the entire population of the country could be lifted by the elevator. In your calculations, assume also that g is constant over the entire height h. answer in Meters

George Smits owns George's Joint, a gas station and convenience store. George is trying to get a better understanding of his business and wants to estimate the mean number of gallons of gasoline sold to his customers. Assume the number of gallons of gasoline sold follows a normal distribution with a population standard deviation of 2.3 gallons. From these records, he randomly selects 60 sales and finds the mean number of gallons sold is 8.6

What is the point estimate of the population mean?
