Suppose a measurement is made on some physical characteristic whose value is known, and let x denote the resulting measurement error. for an unbiased measuring instrument or technique, the mean value of x is 0. assume that any particular measurement error is normally distributed with variance s2. let x1, . . xn be a random sample of measurement errors.

a. obtain the method of moments estimator of s2.

b. obtain the maximum likelihood estimator of s2.

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

answer: when you burn wood, the carbon reacts with the oxygen in the air to create ash and smoke. that is a permanent change you cannot undo that.
