Different groups of 50 graduates of an engineering school were asked the
starting annual salary for their first engineering job after graduation, and the
sampling variability was low. if the average salary of one of the groups was
$65,000, which of these is least likely to be the average salary of another of
the groups?

7

step-by-step explanation:

52 \43 i don't know this i tried

the answer is option a you would get more money.it would be $250.

step-by-step explanation:

for option b 200/2=100=50% 100/2=50=25% 50/5=10=5% it would be $220

graph #4 (last graph) depict the function   f(x)= -m(x-d)^1/5 i

step-by-step explanation:

we know that

m=slope

but in this function slope is -m that means slope is decreasing and it is decreasing by 1/5 points down the x-axis.

which is shown in graph four

a decreasing slope down x-axis by 1/5 points.

hence 4th graph is the right option for this.
