It's in the straight middle, because these two variances are the same, so we just average the means.

We know that the average after four exams, at four exams, is equal to 84.

By average

Same with Z scores, right. Remember, the, the middle of the distribution on Z is zero.

So you know a distribution is perfectly normal if it's, if it has this bell shape and if it's symmetrical around the mean.

It's relatively normal. You see that the mean is a little bit higher than the population mean.

That means that nu is weighted much, much larger than the mu.
