(8) TRUE/FALSE: Circle either T or F. No justification is needed.
(a) (T : F) Each line in R n is a one-dimensional subspace of R n .
(b) (T : F) The determinant of A is the product of the pivots in any echelon form U of A, multiplied by (−1)r , where r is the number of row interchanges made during row reduction from A to U.
(c) (T : F) Adding a multiple of one row to another does not affect the determinant of a matrix.
(d) (T : F) det(A + B) = det(A) + det(B).
(e) (T : F) If the columns of A are linearly dependent, then det A = 0.
(f) (T : F) det AT = (−1) det A.
(g) (T : F) The determinant of A is the product of the diagonal entries in A.
(h) (T : F) If det A is zero, then two rows or two columns are the same, or a row or a column is zero.
(i) (T : F) If two row interchanges are made in succession, then the determinant of the new matrix is equal to the determinant of the original matrix.

Each of the following 13 statements is either (always) True (T)
or (sometimes) False (F). If your answer is sometimes False (F),
please provide a counterexample; that is, give an example where the
statement is not true. If it is always true, you need not give a
proof; merely answer T.

A hypothesis test uses data from a sample to assess a claim about a population.
A randomization distribution will be centered at the value used in the null hypothesis.
“Failing to reject the null hypothesis” and “accepting the null hypothesis” mean the same thing in a hypothesis test’s conclusion.
The p-value is the probability, assuming the alternative hypothesis is true, of obtaining a sample statistic as...
