A particular magazine identified the top accounting firms in 8 geographic regions across a certain country. Even though all 8 regions reported growth in the past year,
region A and region B reported the highest combined growths, with 17% and 25%, respectively. A characteristic description of the accounting firms in these regions
included the number of partners in the firm. The accompanying table contains data on the number of partners. Complete parts (a) through (d) below.

IMPORTANT NOTE: In all of these questions, there are 2 possible ratios A/B and B/AI Our convention is to always assume that the larger variance is in the
numerator (i.e., on top). The correct answer will always be found in this fashion. Similarly, in questions about a critical value, we shall consider the right
(upper) tail.
a. At the 0.01 level of significance, is there evidence of a difference in the variability in numbers of partners for region A accounting firms and…

- The Federal Bureau of Investigation (FBI), as part of its internal security mission, serves as a database for all the reported crimes committed in the United States. One question that might be of interest is does having more police officers reduce the number of homicides? To investigate this claim, the 2013 data from the twenty largest municipal cities was supplied by the FBI's Uniform Crime Report.

- The Toyota Camry is one of the best-selling cars in North America. The cost of a previously owned Camry depends upon many factors, including the model year, mileage, and condition. To investigate the relationship between the car's mileage and the sales price for a 2007 model year Camry, the following data show the mileage and sale price for 19 sales (PriceHub website, February 24,2012). a. Develop a scatter diagram with the car mileage on the horizontal axis and the price on the vertical b. What does the scatter diagram developed in part (a) indicate about the relationship between the two variables? c. Develop the estimated regression equation that could be used to predict the price ($1000s) given the miles (1000s). d. Test for a significant relationship at the .05 level of significance. e.

According to the 2016- 17 Australian Plastics Recycling Survey, the term ‘recycling’ is used in the plastics industry “to cover a range of activities including collection, sorting, reprocessing, export for reprocessing and manufacture of new products.” In order to avoid double-counting materials, survey data is typically collected on the reprocessing stage, which is the stage where waste plastics are converted into a new product (may be finished or semi-finished).arrow_forwardFor unemployed persons in the United States, the average number of months ofunemployment at the end of December 2009 was approximately seven months(Bureau of Labor Statistics, January 2010).
