From the given data sets we shall obtain the answers as follows: <span>301 345 305 394 328 317 361 325 310 362 Re-arrange the data in ascending order: 301, 305, 310, 317,325, 328, 345, 361, 362, 394 from the above we see that:
If a study determines the difference in average salary for subpopulations of mechanical engineers and civil engineers is NOT significant, then the subpopulations of mechanical and civil engineers are not earning different salaries. Study determines that there is not any significant study so thats why both are not earning.
