A confidential and voluntary survey conducted in STA 3024 in the Spring of 1999 asked the students questions about their sex life.

The analysis yielded the following results: y-hat = -18.6 + 1.14x. Which of the following is the best description of the slope of the line?

A. As the number of lifetime sexual partners a student has had increases by 1 person, the student's age will decrease, on average, by 18.6 years.

B. As the number of lifetime sexual partners a student has had increases by 1 person, the student's age will increase, on average, by 1.14 years.

C. As the student's age increases by 1 year, the number of lifetime sexual partners a student has had will decrease, on average, by 18.6 people.

D. As the student's age increases by 1 year, the number of lifetime sexual partners a student has had will increase, on average, by 1.14 people.
