Thank you for posting your question here. I think the question is "
<span>What is the estimated mean for the population? Explain your answer and show your work."
Below is the solution. I hope it helps.
</span>µ= (1*248 +2*567 +3*1402 +4*728 +5*419 +6*456 +7*203)/(1 +2 +3 +4 +5 +6 +7)
<span>=14752/28≈ 526.9</span>
The formula for slope is (x2-x1)/(y2-y1).
we label the points accordingly:
(-7,3) as (x1, y1)
and
(4,-2) as (x2, y2).
now just plug it into the formula.
(-2-3)/(4-(-7))
(-5/11)
the slope is -5/11.
hope this helps! (:
