In just one month in 2001, Natural Resources Canada recorded 215 earthquakes that affected Canada from B.C. to Nunavut to Newfoundland. We would like to determine whether there is a linear relationship between the location of an earth- quake X (measured in degrees latitude north of the equator) and the magnitude of the earthquake Y (measured on the Richter scale). The explanatory and response variables are measured for a sample of 13 earthquakes. The equation of the least squares regression line is ŷ = -3.05+ 0.10x.

- Identify the information given to you in the application problem below. Use that information to answer the questions that follow.For part a) and b), round your answers to two decimal places as needed. For part c) and d), round your answer to the nearest whole number (person). In 2000, the estimated population of Pottsville, USA was 36956. By 2001, the population had grown to 41278. Assuming that the growth is linear, construct a linear equation that expresses the population, P, of Pottsville t years since 2000.P(t)=P(t)= Assuming that the growth is exponential, construct an exponential equation that expresses the population, P, of Pottsville t years since 2000.P(t)=P(t)= If the population of Pottsville is growing at a linear rate, estimate the population in the year 2008.If the population of Pottsville is growing at a linear rate the population in the year 2008 will be approximately people.
