Which of the following statements are true? There may be more than one true statement.

A.

Any linear combination of vectors can always be written in the form Ax for a suitable matrix A and vector x.

B.

Every matrix equation Ax=b corresponds to a vector equation with the same solution set.

C.

If the echelon form of the augmented matrix [A | b][A | b] has a leading entry in every row, then the equation Ax=b is inconsistent.

D.

A vector b is a linear combination of the columns of a matrix A if and only if the equation Ax=b has at least one solution.

E.

If the columns of the matrix A form a linearly independent set, then the equation Ax=b is consistent.

F.

The solution set of a linear system whose augmented matrix is [a1 a2 a3 | b][a1 a2 a3 | b] is the same as the solution set of Ax=bAx=b, if A=[a1 a2 a3 ]A=[a1 a2 a3 ].

A) Which of the following statements are true? Note that there may be more than one correct answer; select all that are true. As the p-value increases, the evidence against the null hypothesis also increases. In hypothesis testing, if the p-value is sufficiently small, then the null hypothesis can be rejected in favour of the alternate hypothesis. If the null hypothesis is true, then the p-value will always be greater than 0.1. If the null hypothesis is false, then the...
