A city’s population has been growing exponentially over the past several years. In 2010, the population was 130,000 people. In the year 2016, it was 160,000 people. Express the population as a function of the number of years since 2010, using the general form ?? = ?? ? ????. What is the predicted population in the year 2020? Round your answer to the nearest whole number.

Question 14 (0.75 points) Suppose that the mean price of a home in Denver, Colorado in 2008 was 225.3 thousand dollars. A random sample of 49 homes sold in 2010 had a mean price of 201.7 thousand dollars. A real estate firm wants to test to see if the mean price in 2010 differs from the from mean price in 2008. Assume that the population standard deviation is 140. Perform the hypothesis test and compute the P-value. Write down your...
