Q:

Camille asked five of her friends how long they studied for the last math test and what grade they received. She found a linear regression equation for the data to be y = 9.6x + 65.8, with x representing hours.What does the 9.6 and the 65.8 mean in the context of this equation?A) 9.6 = the lowest score you can get;65.8 = the highest score you can get B) 9.6 = the number of points you would increase each hour of studying;65.8 = your score if you studied 0 hours C) 9.6 = the number of points you would increase each hour of studying;65.8 = the highest score you can get D) 9.6 = the number of hours you studied;65.8 = your score if you studied 0 hours

Accepted Solution

A:
Answer:B. 9.6 = the number of points you would increase each hour of studying;65.8 = your score if you studied 0 hours Step-by-step explanation:A linear regression equation y = 9.6x + 65.8, with x representing hours. When x = 0, then y = 65.8. This means 65.8 = your score if you studied 0 hoursWhen x = 1, then[tex]y=9.6+65.8=75.4[/tex]is your score after studying one hour.The score increased by [tex]75.4-65.8=9.6,[/tex] so9.6 = the number of points you would increase each hour of studying.
