Chapter 25, Problem 21P

The logistic model is used to simulate population as in

d p d t = k g m ( 1 p / p max ) p

where p = population, k g m = the maximum growth rate under unlimited conditions, and p max = the carrying capacity. Simulate the world's population from 1950 to 2000 using one of the numerical methods described in this chapter. Employ the following initial conditions and parameter values for your simulation: p 0 ( in 1950 ) = 2555  million people,  k g m = 0.026 / yr, and  p max = 12 , 00 million people. Have the function generate output corresponding to the dates for the following measured population data. Develop a plot of your simulation along with these data.

t 1950 1960 1970 1980 1990 2000
p 2555 3040 3708 4454 5276 6079

Find the greatest possible value of the expression (((a+b) ⋆ c) ⋆d) ⋆ e if each star is replaced with one of the operations +, −, and the numbers a, b, c, d, e are -2, -1, 0, 1, 2 in some order. Different stars can correspond to different operations.
In Gallup's Annual Consumption Habits Poll, telephone interviews were conducted for a random sample of 1014 adults aged 18 and over. One of the questions was, "How many cups of coffee, if any, do you drink on an average day?" The following table shows the results obtained (Gallup website, August 6, 2012). Number of Cups per Day 0 1 2 3 4 or more Number of Responses 365 264 193 91 101 Define a random variable x = number of cups of coffee consumed on an average day. Let x=4 represent four or more cups. a. Develop a probability distribution for x. b. Compute the expected value of x. c. Compute the variance of x. d. Suppose we are only interested in adults who drink at least one cup of coffee on an average day. For this group, let y = the number of cups of coffee consumed on an average day. Compute the expected value of y and compare it to the expected value of x.
Ten major college football bowl games were played in January 2010, with the University of Alabama beating the University of Texas 37 to 21 to become the national champion of college football. The results of the 10 bowl games follow (USA Today, January 8, 2010). Bowl Game Score Outback Gator Auburn 38 Northwestern 35 Florida State 33 West Virginia 21 Capital One Penn State 19 LSU 17 Rose Ohio State 26 Oregon 17 Florida 51 Cincinnati 24 Sugar Cotton Alamo Fiesta Mississippi State 21 Oklahoma State 7 Texas Tech 41 Michigan State 31 Boise State 17 TCU 10 Orange Iowa 24 Georgia Tech 14 Championship Alabama 37 Texas 21 Predicted Point Margin Actual Point Margin 5 3 1 12 3 -2 14 3 9 -4 -3 4 229740706 14 10 10 16 The predicted winning point margin was based on Las Vegas betting odds approximately one week before the bowl games were played. For example, Auburn was predicted to beat Northwestern in the Outback Bowl by five points. The actual winning point margin for Au- burn was three points. A…
