Answer:
The test statistics is 
Step-by-step explanation:
From the question we are told that
The data given is
330 620 1870 2410 4620 6396 7822 81028309 12882 14419 16092 18384 20916 23812 25814
The population mean is 
The sample size is n = 16
The null hypothesis is 
The alternative hypothesis is 
The sample mean is mathematically evaluated as

So

=> 
The standard deviation is mathematically represented as

So



=> 
Generally the test statistic is mathematically represented as


From the z-table the p-value is

From the values obtained we see that
so we fail to reject the null hypothesis
Which implies that the claim of the NarStor is wrong
I don’t really understand this put a person with genius role is answering so i hope you get your answer! goodluck
You can compose, or create, a parallelogram (a four-sided shape with two sets of opposite, parallel sides) using two shapes, such as triangles or squares. You can decompose, or take apart, a parallelogram by dividing it from opposite corners, either vertically or horizontally.
First add 1 to each side. It will leave you with an equation like this. 5x=3x -4
Next, subtract 3x from each side. It will leave you with an equation like this. 2x= -4
Lastly, divide each side by 2 so we can get x by itself.
ANSWER: x=-2
Answer:
C Yes, 75+ 2.5*60 = 225
Step-by-step explanation:
The charges for the electrician
1st hour = 75
Additional hours 60
We have 3 1/2 hours of labor
The first hour is 75 dollars
3 1/2 - 1 = 2 1/2
There will be 2 1/2 hours at the 60 dollar rate
75 + 60 * 2.5 =
75 + 150
225
