A researcher is interested in a possible relationship between height and the time it takes to run a 100 meters. With a random sample of 57 people, the researcher finds a Pearson correlation coefficient r = − 0.492.
Group of answer choices
A. There is a very strong correlation between these variables. As height increases, generally the 100-meter run time decreases.
B. There is a very strong correlation between these variables. As height increases, generally the 100-meter run time increases as well.
C. There is no correlation between these variables. As height increases, there is no general trend in what happens with the 100-meter run time.
D. While not very strong, there is a moderate correlation between these variables. In general, as height increases, the 100-meter run time will also increase.
E. While not very strong, there is a moderate correlation between these variables. In general, as height increases, the 100-meter run time will decrease.
