What is the relationship between the attendance at a major league ball game and the total number of runs scored? Attendance figures (in thousands) and the runs scored for 9 randomly selected games are shown below. Attendance Runs 60 16 18 52 57 19 30 43 53 14 3 9 9 16 9 11 12 10 a. Find the correlation coefficient: r = 0.72 Round to 2 decimal places. b. The null and alternative hypotheses for correlation are: Hor=0 H: #0 The p-value is: 0.0289 (Round to four decimal places) c. Use a level of significance of = 0.05 to state the conclusion of the hypothesis test in the context of the study. There is statistically significant evidence to conclude that a game with a higher attendance will have more runs scored than a game with lower attendance. There is statistically insignificant evidence to conclude that there is a correlation between the attendance of baseball games and the runs scored. Thus, the use of the regression line is not appropriate. There is statistically significant evidence to conclude that a game with higher attendance will have fewer runs scored than a game with lower attendance. There is statistically significant evidence to conclude that there is a correlation between the attendance of baseball games and the runs scored. Thus, the regression line is useful.
