6. Passing and Winning in the NFL. The National Football League (NFL) records avariety of performance data for individuals and teams. To investigate the importanceof passing on the percentage of games won by a team, the_following data show theaverage number of passing yards per attempt (Yds/Att) and the percentage of gameswon (WinPct) in a season for a random sample of 10 NFL teams. TeamYds/AttWinPctArizona Cardinals6.550Atlanta Falcons7.163Carolina Panthers7.438Chicago BearsDallas CowboysNew England PatriotsPhiladelphia Eagles6.4507.4508.3817.450Seattle Seahawks6.144St. Louis Rams5.213Tampa Bay Buccaneers6.225a. Develop a scatter diagram with the number of passing yards per attempt on thehorizontal axis and the percentage of games won on the vertical axis.b. What does the scatter diagram developed in part (a) indicate about the relationshipbetween the two variables?c. Develop the estimated regression equation that could be used to predict the percent-age of games won given the average number of passing yards per attempt.d. Provide an interpretation for the slope of the estimated regression equation.e. For the 2011 season, the average number of passing yards per attempt for the Kan-sas City Chiefs was 6.2. Use the estimated regression equation developed in part (c)to predict the percentage of games won by the Kansas City Chiefs. (Note: For the2011 season the Kansas City Chiefs record was 7 wins and 9 losses.) Compare yourprediction to the actual percentage of games won by the Kansas City Chiefs.

Part III- Linear Relationship Scenario: A pediatrician wants to determine the relation that may exist between a child's height and head circumference. She randomly selects eleven 3-year old children from her practice, measures their heights and head circumference, and obtains the data shown below: Height (inches) Head Circumference (inches) 27.75 17.5 24.5 17.1 25.5 17.1 26 17.3 25 16.9 25.75 17.6 26.5 17.3 27 17.5 26.75 17.3 26.75 17.5 27.5 17.5 a. If the pediatrician wants to use height to predict head circumference, determine which variable is the explanatory variable and which is response variable. b. Draw a scatter diagram of the data. c. Draw the best fit line on the scatter diagram. d. Does this scatter diagram show a positive, negative, or no relationship between a child's height and the head circumference?
A veterinarian interested in pet nutrition surveyed owners of a single pet (either a dog, a cat, or a ferret) to ask whether they feed their pet primarily dry pet food, canned pet food, or home-cooked food. The following segmented bar graph shows the distribution of the three types of food for each type of pet. Dog Cat Ferret 0.0 0.2 0.4 0.6 0.8 Relative Frequency Dry Canned 1.0 Home-cooked Which of the following statements about pet owners in the survey is supported by the segmented bar graph? (A) Of all owners who fed their pet primarily dry pet food, the least number owned a cat. (B) More than half of the owners fed their pet primarily canned pet food. (C) Ninety percent of owners fed their pets primarily dry pet food. (D) The number of ferret owners who fed their pets primarily dry pet food was equal to the number of ferret owners who fed their pets primarily home-cooked food. (E) A majority of dog owners fed their pets primarily canned pet food.
3. Consider the following sets of data from Dataset II. For the dataset, determine what type of chart or graph would best represent those data (A-D). Explain your reasoning in detail. Pie chart Line graph Bar graph Scatter plot Dataset II: Carolyn collected data on rates of recycling participation over the last eight years to determine whether her city’s education program has been effective. In 2006, before the education program was implemented, 9% of the city’s residents recycled. Her data follows: Year Participation Rate 2006 9% 2007 13% 2008 17% 2009 22% 2010 28% 2011 31% 2012 32% 2013 30% 2014 31% What type of figure would best represent these data in Dataset II? ________ Reasoning:
Use a scatter plot to display the data shown in the table below. The data represents the number of students per teacher and the average teacher salaries (in thousands of dollars) in 10 school districts. Number of Students per Teacher Average Teacher's Salary 17.2 28.6 17.8 46.6 18.2 32.1 17.4 27.6 18.4 39.8 17.6 32.8 15.0 49.5 17.5 38.4 13.7 42.1 18.0 32.4 1.Construct a scatter diagram. 2.Describe the relation between students per teacher and average teacher salary. A. As the amount of students per teacher increases, the average teacher salary also increases. B. As the amount of students per teacher decreases, the average teacher salary increases. C. There appears to be no relation between students per teacher and average teacher salary.

Assume that a randomly selected subject is given a bone density test. Those test scores are normally distributed with a mean of 0 and a standard deviation of 1. Draw a graph and find the bone density test scores that can be used as cutoff values separating the lowest 10% and highest 10%, indicating levels that are too low or too high, respectively. Sketch the region containing the lowest 10% and highest 10%. Choose the correct graph below. OA. -Za Za Q The bone density scores are ☐ OB. -Za Za (Use a comma to separate answers as needed.
