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.
z= -4
Solve for z by simplifying both sides of the equation then isolating the variable
<h3>Answer:
$186.03</h3>
===================================================
Explanation:
It costs $91.50 for the first 200 copies.
Roger needs 200 more copies to get to 400 total.
He's charged $42 per 100 copies at this point, so he is charged 42*2 = 84 extra dollars to do those extra 200 copies.
Before tax, his total is 91.50+84 = 175.50 dollars.
The sales tax will increase the bill by 6%
To increase by 6%, we use the multiplier 1.06
1.06*175.50 = 186.03
Or you can follow the steps shown in the next section.
-----------------
6% of 175.50 = 0.06*175.50 = 10.53
The sales tax is $10.53
175.50 + 10.53 = 186.03
-----------------
Whichever method you use, you should end up with an after-tax cost of $186.03
The answer is Yes, you can factor this equation.
Answer:
Slope- 5 y-int- (0,0)
Step-by-step explanation:
y=mx+b, where m=slope and b=y-int. m=5, and we don't see a b, so it must be 0.
