The population P (in thousands) of a certain city from 2000 through 2014 can be modeled by P = 160.3e ^kt, where t represents the year, with t = 0 corresponding to 2000. In 2007, the population of the city was about 164,075.

(a) Find the value of k. (Round your answer to four decimal places.)

K=___________

Is the population increasing or decreasing? Explain.

(b) Use the model to predict the populations of the city (in thousands) in 2020 and 2025. (Round your answers to three decimal places.)

2020     P = thousand people
2025     P =   thousand people

(c) According to the model, during what year will the population reach 210,000?

This exercise deals with data from the U.S. Bureau of the Census on populations of major cities.† These data allow us to find how fast the population is growing and when it will reach certain levels. Such calculations are very important, because they indicate the future needs of the population for goods and services and how well the area can support the population.

Consider this scenario: The population of a city increased steadily over a ten-year span. The following ordered pairs show the population x and the year y over the ten-year span in the form (x, y) for specific recorded years. Use linear regression to determine a function y, where the year depends on the population. Round to three decimal places of accuracy. (2500, 2001), (2650, 2002), (3000, 2004), (3500, 2007), (4200, 2011) Predict when the population will hit 13,000. The linear...

The cost of a daily newspaper varies from city to city. However, the variation among prices remains steady with a population standard deviation of $0.20. A study was done to test the claim that the mean cost of a daily newspaper is $1.00. Thirteen costs yield a mean cost of $0.95 with a standard deviation of $0.18. Do the data support the claim at the 1% level? Note: If you are using a Student's t-distribution for the problem, you may...
