Sketch the standard Normal curve for the test statistic and mark off areas under the curve to show why a value of z z that is significant at the 1 % 1% level in a one‑sided test is always significant at the 5 % 5% level. If z z is significant at the 5 % 5% level, what can you say about its significance at the 1 % 1% level?

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
