Answer:
A.
Step-by-step explanation:
From the given information:
If A = m × n matrix
where;
b is a vector in
Then; the statement that doesn't fit and is not related to the other three from the given options is Option A.
This is because the statement in Option A appears to be inconsistent. For the model Ax=b to have a solution, A must be non-singular and b must be in A's column space.
Option c and d are equivalent, also option b and c are equivalent.
Find the z-scores for the two scores in the given interval.
For the score x =391,
.
For the score x = 486,
Now you want the area (proportion of data) under the normal distribution from z = -1 to z = 0. The Empirical Rule says that 68% of the data falls between z = -1 to z = 1. But the curve is symmetrical around the vertical axis at z = 0, so the answer you want is HALF of 68%.
