Decide whether statements (a) through (e) are true or false. Justify each answer. Assume A is an mtimesn matrix and Bold b is in set of real numbers R Superscript m. a. The general least-squares problem is to find an Bold x that makes Upper A Bold x as close as possible to Bold b. Choose the correct answer below. A. The statement is false because the general least-squares problem attempts to find an Bold x such that Upper A Bold xequalsBold b. B. The statement is true because the general least-squares problem attempts to find an Bold x that minimizes
