MATH 54 QUIZ 5-
1. Let S be a subset of an n-dimensional vector space V, and suppose S contains fewer than n vectors. Explain why S cannot span V.
2. Assume that the matrix A is row equivalent to B. Without calculations, list rank A and dim Nul A. Then find bases for Col A, Row A, and Nul A.
3. If A is a 7 × 5 matrix, what is the smallest possible dimension of Nul A?
4. Let A be an m × n matrix. Which of the subspaces Row A, Col A, Nul A, Row AT, Col AT, Nul AT are in Rm and which are in Rn? How many distinct subspaces are in this list?
5. Let
be bases for R2. Find the change of coordinate's matrix from B to C and the change of coordinate's matrix from C to B.
6. Show that {ln 2, ln 3, ln 5} is linearly independent when R is considered as a vector space with scalars in Q.
7. Write anything you like here (comments, questions, suggestions, etc).

The observations come from a distribution
: Let the ordered sample observations be denoted by being the smallest and yn the largest). Our suggested check for normality is to plot the pairs. Suppose we believe that the observations come from a distribution with mean 0, and let w1,..., wn b..
