Answer:
C is the answer
Consecutive angles are supplementary not congruent
Using the z-distribution, the p-value would be of:
b) 0.0086.
<h3>What are the hypothesis tested?</h3>
At the null hypothesis we test if the means are equal, equivalent to a subtraction of 0, hence:
![H_0: \mu_D - \mu_C = 0](https://tex.z-dn.net/?f=H_0%3A%20%5Cmu_D%20-%20%5Cmu_C%20%3D%200)
At the alternative hypothesis, we test if they are different, hence:
![H_1: \mu_D - \mu_C \neq 0](https://tex.z-dn.net/?f=H_1%3A%20%5Cmu_D%20-%20%5Cmu_C%20%5Cneq%200)
<h3>What are the mean and the standard error for the distribution of differences?</h3>
For each sample, they are given as follows:
.
.
For the distribution of differences, it is given by:
.
<h3>What is the test statistic?</h3>
The test statistic is given by:
![z = \frac{\overline{x} - \mu}{s}](https://tex.z-dn.net/?f=z%20%3D%20%5Cfrac%7B%5Coverline%7Bx%7D%20-%20%5Cmu%7D%7Bs%7D)
In which
is the value tested at the null hypothesis.
Hence:
![z = \frac{\overline{x} - \mu}{s}](https://tex.z-dn.net/?f=z%20%3D%20%5Cfrac%7B%5Coverline%7Bx%7D%20-%20%5Cmu%7D%7Bs%7D)
z = -2/0.76
z = -2.63.
Using a z-distribution calculator, for a two-tailed test, with z = -2.63, the p-value is of 0.0086.

Answer: Nonlinear function
Step-by-step explanation:
Answer:
$475
Step-by-step explanation:
There are 3 possible accident in this question
3% chance of losing $2000
0.1% chance of losing $150,000
96.9% chance of losing $0
Then the expected value that you will lose is:
3%* $2000 + (0.1% * $15000) + (96.9% * $0)= $75
Profit made by subtracting the price with the lose. If the company want average profit $400, the charge should be:
average profit = premium price - average lose
premium price= average profit + average lose
premium price= $400 + $75 = $475
