b. Is the answer:)
Answer: D: The model predicts that a person who does not walk each day will score about 48.1 on the test.
Step-by-step explanation:
Given: A psychologist collects data on the time, w, in minutes, people walk each day and their scores, t ,on a stress test.
She finds that there is a negative linear association between w and t that is best modeled by the equation
.
When we put w=0 minutes, t=48.1
It implies that if any patient doesn't walk will score 48.1.
Hence, the model predicts that a person who does not walk each day will score about 48.1 on the test.
It will be 25.7435 i hope that the right answer
25,5 minutes=25,5/60 hours=0,425 hours
3,75/0,425 miles/hour =8,8235≈8,82 miles/hour
