The Medassist Pharmaceutical Company uses a machine to pour cold medicine into bottles in such a way that the standard deviation of the weights is 0.15 oz. A new machine is tested on 71 bottles, and the standard deviation for this sample is 0.12 oz. The Dayton Machine Company, which manufactures the new machine, claims it fills the bottles with less variation. At the 0.05 significance level, test the claim made by the Dayton Machine Company.
Answers
Answer:
hello some part of your question is missing below is the missing part
If Dayton's machine is being used on a trial basis, should its purchase be considered? C.V.(S) = Test Statistic= P-Value= Decision: Conclusion:
answer :
i ) Cv(s) = 51.739
ii) T = 44.8
iii) p-value = 0.0082
iv) we do not fail to reject H0 ( since p-value < 0.05 )
v ) The new machine fills the bottles with a lesser variation
Step-by-step explanation:
we will test the hypothesis in regards to the standard deviation of the population
The hypothesis are
H0 : б = 0.15
Ha : б < 0.15
hence at ∝ = 0.05 where n = 71
i) critical point for left sided test = [tex]x^2_{1-\alpha } , n - 1[/tex]
hence Cv(s) = 51.739
ii) Test statistic = T = ( n - 1 ) s^2 / б^2
s = 0.12 , n = 71 , б = 0.15
hence T = 44.8
iii) P-value = p ( [tex]x^{2} _{70}[/tex] < 44.8 ) = 0.0082
iv ) Decision : we do not fail to reject H0 ( since p-value < 0.05 )
v ) conclusion : The new machine fills the bottles with a lesser variation

Answer:
I can's make out the line, but, you can plot two points, (try to make them whole numbers ie (3,6), (4,8)), subtract the point with the smallest x value from the other point ((4,8)-(3,6)=(1,2)) Divide the new y, by the new x (2/1), and you have your slope.

Step-by-step explanation:
slope is the change of y / change of x
.
we can pick any points and find the changes in y and x
lets pick (0 , 0) and (5 , 6) .
the change of y = 6-0 = 6.
the change of x = 5-0 = 5.
so the slope of the line is 6/5
