A researcher conducted a survey of 300 voting adults at a particular party fund-raiser to estimate the average amount of money electorates contribute to candidates of their choice each election cycle. The data is normally distributed, with the highest amount being $10,250 and the lowest amount being $100 The sample mean is $225. What is the margin of error (ME), rounded to the nearest hundredth?

step-by-step explanation:

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
