Answer:
The p value for this case is given by:
For this case the p value is a very low value compared to the significance level of 0.1 so then we can reject the null hypothesis and we can conclude that the true mean is significantly less than 25 at 10% of significance.
Step-by-step explanation:
Information given
represent the sample mean
represent the population deviation
sample size
represent the value to verify
represent the significance level
tzwould represent the statistic
represent the p value
System of hypothesis
We want to test the hypothesis that the true mean is lower than 25 and the system of hypothesis are:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
Replacing the info given:
The p value for this case is given by:
For this case the p value is a very low value compared to the significance level of 0.1 so then we can reject the null hypothesis and we can conclude that the true mean is significantly less than 25 at 10% of significance.

Answer:
![\huge\boxed{-2}](https://tex.z-dn.net/?f=%5Chuge%5Cboxed%7B-2%7D)
Step-by-step explanation:
Use any two points from the line.
<u>Let them be: </u>
(x1,y1) = (0,-2)
(x2,y2) = (-1,0)
Now,
![\displaystyle Slope = \frac{y_2-y_1}{x_2-x_1} \\\\Slope = \frac{0-(-2)}{-1-0} \\\\Slope = \frac{2}{-1} \\\\Slope = -2\\\\\rule[225]{225}{2}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20Slope%20%3D%20%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%20%5C%5C%5C%5CSlope%20%3D%20%5Cfrac%7B0-%28-2%29%7D%7B-1-0%7D%20%5C%5C%5C%5CSlope%20%3D%20%5Cfrac%7B2%7D%7B-1%7D%20%5C%5C%5C%5CSlope%20%3D%20-2%5C%5C%5C%5C%5Crule%5B225%5D%7B225%7D%7B2%7D)

Answer:
'linear decreasing' best describes interval C on the graph shown.
Step-by-step explanation:
Note: <em>The missing graph is attached below. </em>
From the attached graph, it is easy to figure out that the interval C on the graph shown is showing a straight line. So the graph of the function would be linear.
Also on the interval C, the value of y is decreasing as the value of x increase. So, the slope of the straight line would be negative.
So the interval C indicates that the function is decreasing there.
Therefore, 'linear decreasing' best describes interval C on the graph shown.
You can solve this by cross multiplying and dividing. If you set 104/125 = x/100. 104 * 100= 10400 and you divide that by 125 and get 83.2, so the answer is 83.2% of the guests invited showed up.
