Answer:
Step-by-step explanation:
Given that a professor sets a standard examination at the end of each semester for all sections of a course. The variance of the scores on this test is typically very close to 300.

(Two tailed test for variance )
Sample variance =480
We can use chi square test for testing of hypothesis
Test statistic = 
p value = 0.0100
Since p <0.05 our significance level, we reject H0.
The sample variance cannot be claimed as equal to 300.

Step-by-step explanation:
First of all we do not know how many childen are in the Martin Family

=$160
So depending on how each child sends and how many children will determine which kid will have most of the money left
You cannot find the percent error of data without knowing the true length of the rope, as percent error is essentially a comparison between what you measured and what it actually is.
We have that
the original (x,y) coordinates are being moved to the left by 3 units and up by 5 units.
therefore
the answer is the option
<span>(x, y) → (x – 3, y + 5)</span>
