Answer:
Step-by-step explanation:
Let X be the length of time between billing dates and checks received and deposited for non-delinquent accounts of an oil company’s monthly credit card customers
X has mean 13.5 and sigma 3 days
Sample size = n =36, x bar = 13
![H_0: x bar = 13.5\\H_a: x bar](https://tex.z-dn.net/?f=H_0%3A%20x%20bar%20%3D%2013.5%5C%5CH_a%3A%20x%20bar%20%3C13.5)
(One tailed test at 0.025 sign. level)
Mean diff = -0.5
Since sigma is known z test can be used
Std error =![\frac{\sigma}{\sqrt{n} } =0.5](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%20%7D%20%3D0.5)
Z statistic = -0.5/SE= -0.1
p value = 0.920
p>0.025 hence accept null hypothesis.
My conclusion is there is no statistical evidence that lock box reduced the mean time.
The answer would be irrational
Answer:
When simplified this equation equals 8.
Step-by-step explanation:
Let me show you my work.
4 ( 3.5 - 1.5 ) = 4 ( 2 )
4 ( 2 ) = 8 because 4 times 2 = 8
Hope this helps. . .

For any inscribed quadrilateral, the opposite angles add to 180
(angle PMN) + (angle NOP) = 180
(8x-24) + (4x) = 180
12x-24 = 180
12x-24+24 = 180+24 ..... add 24 to both sides
12x = 204
12x/12 = 204/12 ..... divide both sides by 12
x = 17
angle NOP = 4x
angle NOP = 4*17
<h3>
angle NOP = 68 degrees</h3>
He has 4 choices
