Answer and Explanation:
Given : A lab technician is tested for her consistency by taking multiple measurements of cholesterol levels from the same blood sample.
The target accuracy is a variance in measurements of 1.2 or less. If the lab technician takes 16 measurements and the variance of the measurements in the sample is 2.2.
To find :
1) Does this provide enough evidence to reject the claim that the lab technician’s accuracy is within the target accuracy?
2)Compute the value of the appropriate test statistic ?
Solution :
1) n=16 number of sample
The target accuracy is a variance in measurements of 1.2 or less i.e.
The variance of the measurements in the sample is 2.2 i.e.
According to question,
We state the null and alternative hypotheses,
Null hypothesis
Alternative hypothesis
We claim the alternative hypothesis.
2) Compute the value of the appropriate test statistic.
Using Chi-square,
Therefore, The value of the appropriate test statistic is 27.5.

A = {1,2,3,4}
Subset =
Where n is the number of elements in the set
There are 4 elements in the set
Subset =
Subsets = 16
Answer: MAYBE <em>its 126</em>
Step-by-step explanation: The answer that I believe is- uh- idk. But what I know is that Terrell has 340 in total. He reads 253 in total also. But the question is "How many pages did Terrell read between lunch and dinner". Well I don't get this question very good but I think you subtract 253 to 127 which you get 126. If you don't think this is right, do 126 plus 127 which is 253. If I get this answer wrong I'm sorry, but this question is confusing.
2(2x - 5) = 3x + x - 2x
Distribute the 2.
4x - 10 = 3x + x - 2x
Combine like terms.
4x - 10 = 2x
Subtract 4x from both sides.
-10 = -2x
Divide by -2.
5 = x
x = 5
