To find the answer for this question:

x^2 + 8x 15/x - 4xx^2 - 16/2x + 6

Apply the exponent rule:
x^2 + 8x + 15/x - 4x^3 - 16/2x + 6

Divide the numbers: 16/2 = 8:
x^2 + 8x + 15/x - 4x^3 - 8/x + 6

Apply the rule: a/c +/- b/c = a +/- b/c
x^2 + 8x + 15-8/x - 4x^3 + 6

After you subtract the numbers: 15 - 8 from the fraction that equals to 7:
x^2 + 8x + 7/x - 4x^3 + 6

So, your answer would be: x^2 + 8x + 7/x - 4x^3 + 6.

When testing for differences between treatment means, a confidence interval is computed with __________________?

KIM [24]

The confidence interval is based on mean square error. The mean squared error (MSE) of an estimator measures the average of the squares of the errors or deviations. MSE is calculated by the formula attached in the picture, where Xbar is a vector of predictions, X is the vector of predicted values.
