The following table shows the number of new (single-unit) houses started, in thousands, in the different regions of the United States during 2012-2014. Take S to be the set of all housing starts represented in the table, and label the sets representing the housing startsin each row and column as shown (so, for example, N is the set of all housing starts in the Northeast during 2012-2014).2012 (A)2013 (8)2014 (C)TotalNortheast(N)OBUTOANTOcnrOBOTOAUT50Compute its cardinality.60Use symbols to describe the given set.thousand50160Midwest South(M) (S)90100110300280330350960West(W)110130150390Total530the set of housing starts in 2013 excluding housing starts in the the South6206601,810

A state fisheries commission wants to estimate the number of bass caught in a givenlake during a season in order to restock the lake with the appropriate number ofyoung fish. The commission has information on the seasonal catch (CATCH) inthousands of bass per square mile; the size of the lake in square miles (SIZE); thenumber of lakeshore residences per square mile (RESIDENCE); the number of livingplaces for bass (i.e. weed beds, sunken trees, drop offs etc.) (STRUCTURE) andACCESS a dummy variable equal to 1 if the lake has public access and 0 if not. What do you think are the expected signs of the regression coefficients?Justify your choice. Using R-studio, estimate the multiple linear regression model. ALL input codes and output tables should be provided.(b) Is the overall regression equation statistically significant at the 1% level?Justify your answer. Ensure that you state the null hypothesis(es) and thedecision rule in your analysis.(c) Find and interpret a 95% confidence…
There are eight wires which need to be attached to a circuit board. A robotic device will attach the wires. The wires can be attached in any order, and the production manager wishes to determine which order would be fastest for the robot to use. Use the multiplication rule of counting to determine the number of possible sequences of assembly that must be tested. (Hint: There are eight choices for the first wire, seven for the second wire, six for the third wire, etc.)
