3) Identify two statistics that the student could use to summarize the variable.

a) Mean or Median

b) Mean or Proportions

c) Mean or Mode

d) Median or Mode.

Explanation to the answer:

1) The variable measured on each student is the number of hours of TV watched

2) The variable is the amount of time, therefore it is quantitative.

3)  Quantitative data can be used compare the exact size and extent of difference in two quantities.

Determine if the columns of the matrix form a linearly independent set. Justify your answer. Choose the correct answer below. A.
kondaur [170]

Th matrix is missing. The matrix is :

\begin{bmatrix}1 &-4  &4 \\ -4 &16  & 4 \end{bmatrix}

Solution :

The column of the matrix are \begin{bmatrix}1\\ -4\end{bmatrix} , \begin{bmatrix}-4\\ 16\end{bmatrix}, \begin{bmatrix}4\\ 4\end{bmatrix}

Now each of them are vectors in $IR^2$. But  $IR^2$ has dimensions of 2. But there are 3 column vectors, hence they are linearly dependent.

Therefore, the column of the given matrix does not form the \text{linearly independent set} as the set contains \text{more vectors} than there are entries in each vector.

Therefore, option (D) is correct.
