Explanation Elementary row operation *Row : The third elementary row operation is row multiplication. It performs multiplication or division of a row element by nonzero number. In a matrix, the solution will not be changed if a row is multiplied or divided by a nonzero constant. It stores the result in the target row. It is represented as, *Row ( 2 , [ A], 1 ) Where [A] represents the matrix. 2 is the scalar and 1 is the target row. It multiplies the scalar with the elements in row 1 and store the result in row 1. Example: Consider a 3 × 3 matrix. [ A] = [ 1 0 2 5 3 1 2 3 4 ] Perform the row multiplication operation *Row ( 2 , [ A], 1 ) . The resultant matrix is, [ A] = [ 2 0 4 5 3 1 2 3 4 ] Calculation: The matrix given is, [ D ] = [ 1 0 − 8 2 8 0 1 − 1 3 2 0 0 2 0 10 0 0 − 2 1 6 ] We need to obtain 1 in the row 3 and column 3

Suppose that you want to estimate the mean monthly gross income of all households in your local community. You decide to estimate this population parameter by calling 150 randomly selected residents and asking each individual to report the household’s monthly income. Assume that you use the local phone directory as the frame in selecting the households to be included in your sample. What are some possible sources of error that might arise in your effort to estimate the population mean?
