Random groups of 25 graduates of a school of nursing were asked the
starting annual salary for their first nursing job after graduation. The
sampling variability was low. If the average salaries of several of the groups
were close to $69,000, which of these is least likely to be the average salary
of another of the groups?

The answer is the C ) 79.000

Step-by-step explanation:

answer: approximately 206 bones

i hope this u out a branlist and a would be greatly appreciated :

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
