Question

Researchers collect data on 5,134 American adults younger than 60. They measure the reaction times (in seconds) of each subject to a stimulus on a computer screen and how many years later the subject died.

a)The researchers are interested in whether reaction time can predict time to death (in years).
b)The researchers found that people with slower reaction times tended to die sooner. In a scatterplot of the reaction time and the number of years to death, you expect to see

Answer 1

In a scatterplot of the reaction time and the number of years to death, a negative correlation would be expected.

Step-by-step explanation:

In a scatterplot of the reaction time and the number of years to death, you would expect to see a negative correlation.

This means that as reaction time increases, the number of years to death decreases.

You can visually observe this relationship by plotting the data points on a scatterplot and seeing if they form a downward sloping pattern.
