An economist wants to compare the economic growth rate (%) within 50 kilometers and 100 kilometers to cities in a country. He collected 6 cities of the country, and calculated the growth rates with 50km and 100km as shown in the following table. Choose an appropriate test to validate that regions within 100km have higher economic growth rate than the regions within 50km to cities. You can make certain assumptions, but need to write to indicate your assumption. Show calculations by hand.
The tuition in the school year 2012–2013 at a certain university was $15,000. For the school year 2017–2018, the tuition was $17,850. Find an exponential growth function for tuition T (in dollars) at this university t years after the 2012–2013 school year. (Round your values to four decimal places.)
T =
Assuming it increases at the same annual rate, use the function to predict the tuition (in dollars) in the 2021–2022 school year. (Round your answer to the nearest integer.)

- Let' pretend that in an American city there were 2000 new cases on Monday which is a 12% decrease from two weeks ago. So it appears that new covid cases are going down (wahoo! with a two-week trend of -12%. Curious... how many new cases were there two weeks ago? (don't round for accuracy) c) Write a linear/exponential equation that models this situation (consistent with your choice above). Time is the explanatory variable, and New Covid Cases is the response variable. D. Explain what the slope/multiplier (consistent with your choice above) means in this context of the problem.
