7. (2 points) The regression line that gives the linear relationship between the average temperature and the number of days of school missed is predicted number of days of school missed -18.16 0.42 (average temperature) Which of the following is the correct interpretation of the slope of this regression line? (A) If the average temperature is 0.42, then the predicted number of days of school missed is 18.16 days (B) If the number of days of school missed decreases by 0.42 days, then the predicted average temperature (C) If the number of days of school missed increases by 1 day, then the predicted average temperature increases (D) If the number of days of school missed increases by 1 day, then the predicted average temperature (E) If the average temperature increases by 1 degree, then the predicted number of days of school missed (F) If the average temperature increases by 1 degree, then the predicted number of days of school missed increases by 18.16 degrees by 18.16 degrees. decreases by 0.42 degrees increases by 18.16 days. decreases by 0.42 days.

Explanation / Answer

From regreesion line

slope=-0.42

change in y/change in x

change in days of school missed/average temp=-0.42

means for unit increase in average temparture ,days of school missed missed decreases by 0.42

OPTION F

select option F
