^ Consider the estimated relationship: Y = 50 + 50X. 1-The average level of Y, if X = 0, is 50. 2-For each unit increase in $\alpha$, Y will increase by 50 units. 3-For each unit increase in X, Y will increase by 50 units.
A)1
B)2
C)3
D)1 and 2
E)1 and 3

Question

Quizplus · Accepted Answer

1. The intercept of the estimated relationship (the value of Y when X = 0) is equal to 50, so statement 1 is true.
2. The coefficient on X in the estimated relationship is equal to 50, so statement 3 is true.
Therefore, the correct choice is E, as both statement 1 and statement 3 are true. Statement 2 is incorrect, as it refers to a variable that is not mentioned in the estimated relationship.
