Chapter 3, Problem 1RE, Support your local artist: Following are the annual amount federal support In millions of dollars)

Find the mean annual amount of federal aid from 2006 through 2012
Find the median annual amount of federal aid from 2006 through 2012.

Definition Definition Middle value of a data set. The median divides a data set into two halves, and it also called the 50th percentile. The median is much less affected by outliers and skewed data than the mean. If the number of elements in a dataset is odd, then the middlemost element of the data arranged in ascending or descending order is the median. If the number of elements in the dataset is even, the average of the two central elements of the arranged data is the median of the set. For example, if a dataset has five items—12, 13, 21, 27, 31—the median is the third item in ascending order, or 21. If a dataset has six items—12, 13, 21, 27, 31, 33—the median is the average of the third (21) and fourth (27) items. It is calculated as follows: (21 + 27) / 2 = 24.

In 2011 home prices and mortgage rates dropped so low that in a number of cities the monthly cost of owning a home was less expensive than renting. The following data show the average asking rent for 10 markets and the monthly mortgage on the median priced home (including taxes and insurance) for 10 cities where the average monthly mortgage payment was less than the average asking rent (The Wall Street Journal, November 26–27, 2011).Click on the datafile logo to reference the data. Enter negative values as negative numbers. a. Develop the estimated regression equation that can be used to predict the monthly mortgage given the average asking rent (to 2 decimals).The regression equation is:Mortgage ($) = + Rent ($)

Option 1: Inyestigate salaries in a career that you choose in cities across the country. Use the table to help organize your information. • Choose 5 cities in the United States. • Choose a career you would like to investigate. Find the average salary for the career you are investigating for each of those cities. o Include a link to the sources of your information. • Find a way to compare the cost of living in each of those cities. You can use CPI numbers like you did in Lesson 5B (this link may help: https://www.bls.gov/regions/subjects/consumer-price- indexes.htm) or other sources to find the cost of a "basket of goods" that is relevant to your search. o Include links to the sources of your information. Based on your findings, compare and contrast the value of the salary in each city. o You may want to use a table or spreadsheet like you did in lessons 5A or 5B. Include this in your submission. • Why do you think the value of the salary paid for the same career may be different in…
