Considering the one-sided p-value, the p-value for a two-sided test would be of 0.20.
<h3>How to find the p-value of a test?</h3>
It depends on the test statistic z, as follows:
- For a left-tailed test, it is the area under the normal curve to the left of z, which is the p-value of z.
- For a right-tailed test, it is the area under the normal curve to the right of z, which is 1 subtracted by the p-value of z.
- For a two-tailed test, it is the area under the normal curve to the left of -z combined with the area to the right of z, hence it is 2 multiplied by 1 subtracted by the p-value of z, which means that <u>the p-value for a two-tailed test is </u><u>twice </u><u>the p-value of a one-tailed test</u>.
In this problem, for the one-tailed test, the p-value is of 0.1, hence the p-value for a two-sided test would be of 0.20.

Answer:
sinA=15/17 and cosA=8/17
Step-by-step explanation:
sine is opposite side over hypotenuse and cosine is adjacent side over hypotenuse
Since 8/12 is a proper fraction, it cannot be written as a mixed number. However, 8/12 can be simplified to <u>2/3</u>.
Answer, z10
Step-by-step explanation:
Answer:
<u><em>X = -1</em></u>
<u><em>Step-by-step explanation:</em></u>
- <u><em>Add x to both sides.</em></u>
- <u><em>8x + 1 + x = -8</em></u>
- <u><em>Combine 8x and x to get 9x.</em></u>
- <u><em>9x + 1 = -8</em></u>
- <u><em>Subtract 1 from both sides</em></u>
- <u><em>9x = -9</em></u>
- <u><em>Divide both sides by 9 </em></u>
- <u><em>x = -9/9</em></u>
- <u><em>x = -1</em></u>
