:0 F1 @ 2 F2 W S For major league baseball teams, is there a relationship between player payrolls and gate money? Here are data for each of the National League teams for the year 2002. The variable x denotes the 2002 player payroll (in millions of dollars), and the variable y denotes the mean attendance (in thousands of fans) for the team's home games that year. The data are plotted in the Figure 1 scatter plot.

Teen Birth Rate The birth rate in 2013 for U.S. girlsages 15 to 19 was the lowest since the governmentbegan tracking the statistic in 1940. The highest birthrate for U.S. teens was 96.3 per 1000 girls in 1957.In 2013, the birth rate was lowest at 26.3. Let x equalthe number of years after 1950.a. What is the slope of the line joining the points(7, 96.3) and (63, 26.3)?b. What is the average rate of change in the birth rateover this period?c. What does this average rate of change tell aboutthe birth rate?d. Use the slope from part (a) and the birth rate from2013 to write the equation of the line. Let x represent the number of years after 1950.(Source: Centers for Disease Control and Prevention)
Which of the slopes matches best with the slope of the data in the scatter plot? would it be m = 3/8?, m = 8/3?, m = - 3/8? or would it be m = - 8/3???

Flash Player version 10 or higher is required for this question. You can get Flash Player free from Adobe's website. (b) Would you say the correlation is low, moderate, or strong? low moderate strong Would you say the correlation is positive or negative? positive negative (c) Use a calculator to verify that x = 67, x2 = 1265, y = 644, y2 = 93,546, and xy = 10,544. Compute r. (Round your answer to three decimal places.) As x increases from 3 to 26 months, does the value of r imply that y should tend to increase or decrease? Explain your answer. Given our value of r, y should…
