Answer:
Answer: The estimated equation is shown in the scattered plot diagram attached to the answer supplied
Step-by-step explanation:
(a) Attached scattered plot diagram
(b) Estimated regression equation:
Rating = 3.204 + 0.076 EXPER
b1= 3.204,
b2= 0.076
Se(b1)= 0.709
Se(b2) = 0.044
n=2
The coefficient of EXPER =0.076. This implies that the quality rating will increase by 0.076.
N is 7.5 because prq is 3x the size of abc
If the discriminant is a positive number, there will be 2 possible solutions. If you replace the entire section of b²-4ac with 16, you will see that the equation becomes; (-b+-√16)/2a --> leading to an answer with the + and another with the -.
If the discriminant is 0, there will be 1 possible solution, (again replace this into the discriminant value) (-b)/2a ---> this formula is used to also find the x coordinates of a vertex, fyi.
If the discriminant is a negative number, there will be no solution (since squareroot of a negative number is not possible)
