Apsychologist collects data on the time, w, in minutes, people walk each day and their scores, t ,on a stress test. the scores are from 0 to 100, with higher scores meaning more stress. she finds that there is a negative linear association between w and t that is best modeled by the equation t=β2.5w+48.1 .
what is the meaning of 48.1 in this equation?
a: the people in the study walked an average of 48.1 minutes each day.
b: for each additional minute spent walking, the model predicts that a person's score on the stress test will go down by about 48.1 points.
c: the people who walked each day had an average score of 48.1 on the stress test.
d: the model predicts that a person who does not walk each day will score about 48.1 on the test.
