Different groups of 50 graduates engineering were ask the starting annual salary of their first entering job after graduation, and the sampling variability was low. if the average salary of one of the groups was $53,000, which of these is least likely to be the average salary of another of the groups? a- $54,000 b- $53,000 c- $55,000 d- $41,000

least likely option comes out to be option D.

Step-by-step explanation:

correct answer is option D.

As in the question it is given that the average salary of one group is  $53,000.

and,

it is also stated that the  sampling variability is very low which means the deviation from the mean will be very low .

when look at the options all the option A , B , C  are very much closer to $53,000 and the only option left is $41,000 which is very much deviated

hence,the least likely option comes out to be option D.

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1
