Extracted text: Question 11 W Baseball statisticians studied how often triples (a certain event in a baseball game) occurred in professional games played between 1947 and 2017. A 98 percent confidence interval to estimate the slope of the linear regression line relating the year, x, and the mean number of triples per game, y, yielded (-0.006, –0.002). A check shows that the conditions necessary for inference for the slope of the regression line are met. Based on the confidence interval, which of the following claims is supported? A The mean number of triples per game is between 0.002 and 0.006. в The number of triples per game has increased, on average, per year. There is no linear relationship between the mean number of triples per game and year. D There is a negative linear relationship between the mean number of triples per game and year. E A conclusion cannot be made about the relationship between year and mean number of triples per game because the values are close to 0.
