Annie walks 15 feet away from her house and places a mirror on the ground. She backs 4 feet away from the mirror so that she can
see the tip of the roof. Annie's eyes are 5 feet above the ground. Annie and the house are both perpendicular to the ground. The angles between the top of the house, the mirror, and the ground and between Annie's eyes, the mirror, and the ground are congruent
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.
