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 60 16 Runs 14 3 18 52 57 19 30 43 53 9 9 16 9 11 12 10 Round to 2 decimal places a Find the correlation coefficient r 0 72 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 a 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
