Question 1141389
<br>
Choice A is a single value; it is not a range.<br>
Choice C says the heights are greater than 44 and greater than 72 inches.  That is equivalent to saying the height is greater than 72 inches.  That is not true.<br>
You will NEVER see a range of values presented in the form a < x > b or a > x < b.<br>
Choice D says the heights are less than 44 inches and greater than 72 inches; that is self-contradictory and so is nonsense.<br>
Choice B is the correct form for the answer.  It says the heights are greater than or equal to 44 inches and less than or equal to 72 inches.<br>
You will almost ALWAYS see a range of values shown this way.  The same range could correctly be presented as 72 >= h >= 44; but you will rarely (if ever) see it shown that way.
