An agent for a residential real estate company in a large city has the business objective of developing more accurate estimates of the monthly rental cost for apartments. Toward that goal, the agent would like to use the size of an apartment, as defined by square footage to predict the monthly rental cost. The agent selects a sample of 25 apartments in a particular residential neighborhood and collects the following data:     Size (square feet) Rent ($) 850 1950 1450 2600 1085 2200 1232 2500 718 1950 1485 2700 1136 2650 726 1935 700 1875 956 2150 1100 2400 1285 2650 1985 3300 1369 2800 1175 2400 1225 2450 1245 2100 1259 2700 1150 2200 896 2150 1361 2600 1040 2650 755 2200 1000 1800 1200 2750   Make a Normal Probability Plot and a Residual plot of the Residuals (Y axis) vs. Apartment Size (X axis).  Based on these results, evaluate whether the assumptions of regression have been seriously violated.

A statistics instructor asks each student in his classes to report how much the student spent on textbooks for the semester.  The figures reported by students are shown below.   725 735 555 420 385 480 505 270 405 285 585 450 515 560 500 395 545 595 365 455 505 345 555 485 560 475 520 455 355 590 550 495 505 505 495 465 370 355 480 385 515 605 480 410 485 560 475 350 465 435 455 380 320 535 565 520 510 495 485 650 490 295 555 540 565 490 570 380 610 600 390 375 390 335 525 445 540 490 485 555 440 560 405 590 520 470 560 510 340 385 585 635 415 455 590 385 505 510 545 405 470 560 495 515 495 595 565 615 470 680 465 470 310 470 505 465 375 360 650 460 560 500 375 500 370 415 490 440 470 525 535 640 385 475 425 595 505 365 485 495 390 380 585 690

The following data represent the inventory figures for 55-gallon fish tanks at an aquarium. 55-Gallon Fish Tanks Inventory   Amount January 1 Beginning Inventory 46 units @ $38.00   March 12 Purchase 70 units @ $36.50   July 19 Purchase 135 units @ $39.70   September 2 Purchase 65 units @ $41.75   Fish Tanks Available for Sale:   Cost of Tanks Available for Sale:   (a) How many fish tanks did the aquarium have available for sale?   fish tanks (b) Calculate the total cost (in $) of the tanks available for sale. $  (c) If physical inventory on December 31 showed 88 tanks on hand, calculate their dollar value by using FIFO. $  (d) Calculate the value of the 88 tanks by using LIFO (in $). $  (e) Calculate the dollar value of the 88 tanks by using the average cost method (Round your answer to the nearest cent). $

An agent for a residential real estate company in a suburb located outside a major city has the business objective of developing more accurate estimates of the monthly rental cost for apartments. Toward the goal, the agent would like to use the size of an apartment, as defined by square footage to predict the monthly rental cost. The agent selects a sample of 8 one-bedroom apartments and the data are shown.
