Questions
State whether the following statement is True or False:
The following data is not consistent: byx + bxy =1.3 and r = 0.75
State whether the following statement is True or False:
If byx + bxy = 1.3 and r = 0.75 then the given data is inconsistent.
Options
True
False

Solution
This statement is true.
Explanation:
The given data is inconsistent because the equation byx + bxy = 1 + r2 should hold. Here 1 + (0.75)2 = 1.5626, but the given sum is 1.3, which contradicts the formula.
