Please help me answer these questions given the multiple choice selection,Thanks!!!

1.A researcher is interested in how age influence driving accidents. She measures age in years and driving accidents as number of accidents in a single calendar year.Here is her data

age= 15,16,15,21,45,32

accidents = 2,3,1,1,0,0

Which choice represents Beta (), for the regression equation?

a.-7.2973

b.-0.72973

c.-0.072973

2.A researcher is interested in how age influence driving accidents. She measures age in years and driving accidents as number of accidents in a single calendar year.Here is her data

age= 15,16,15,21,45,32

accidents = 2,3,1,1,0,0

Answer the following questions

Which choice represents Alpha (), for the regression equation?

a.29.18018

b.2.918018

c.0.2918018

3.A researcher is interested in how age influence driving accidents. She measures age in years and driving accidents as number of accidents in a single calendar year.Here is her data

age= 15,16,15,21,45,32

accidents = 2,3,1,1,0,0

Answer the following questions

Which is the correct resulting estimated regression equation?

a.Y=-0.072973 + 2.918018X

b.X=2.918018 + -0.072973Y

c.Y=2.918018 + -0.072973X

4.A researcher is interested in how age influence driving accidents. She measures age in years and driving accidents as number of accidents in a single calendar year.Here is her data

age= 15,16,15,21,45,32

accidents = 2,3,1,1,0,0

Answer the following questions

Which of the following choices is the correct interpretation of alpha ()?

a.When age is equal to zero, predicted number of accidents is equal to 2.918 accidents a year.

b.When age is equal to zero, the number of accidents is equal to 2.918 accidents a year.

c.When number of accidents is equal to zero, predicted age of driver is 2.918 years.

5.A researcher is interested in how age influence driving accidents. She measures age in years and driving accidents as number of accidents in a single calendar year.Here is her data

age= 15,16,15,21,45,32

accidents = 2,3,1,1,0,0

Answer the following questions

Which the following choices is the correct interpretation of beta()?

a.When age increases by one year, predicted number of accidents that a person will be involved in goes down by 7 accidents a year.

b.When age increases by one year, predicted number of accidents that a person will be involved in goes down by .073 accidents a year.

c.When age increases by zero years, predicted number of accidents that a person will be involved in goes down by .073 accidents a year.
