Answer:
The three consecutive even integers are 4,6,8
Step-by-step explanation:
Let the three consecutive even integers be 2x, 2x+2, 2x + 4
Middle number = 2x +2
2x + 2x+2 + 2x + 4 = 4* (2x+2) - 6
6x + 6 = 4*2x + 4*2 - 6
6x + 6 = 8x + 8 -6
6x + 6 = 8x + 2
6x - 8x = 2 -6
-2x = -4
x = -4/-2
x = 2
The three consecutive even integers are
2x = 2*2 = 4
2x+2 = 2*2 +2 =4 + 2 = 6
2x + 4 = 2*2+4 = 4+4 = 8
Answer:
99% confidence interval estimate of the mean weight time for a population with drug treatments
(79.11 , 112.69)
Step-by-step explanation:
<u><em>Step(i):</em></u>-
Given data mean of the Population = 104 minutes
Given sample size 'n' =14
Mean of the sample(x⁻) = 95.9 minutes
Given Standard deviation = 24.4 minutes
<u><em>Step(ii)</em></u>:-
99% confidence interval estimate of the mean weight time for a population is determined by


On calculation , we get
(95.9 -16.79 , 95.9 +16.79)
(79.11 , 112.69)
<u><em>Conclusion:</em></u>-
99% confidence interval estimate of the mean weight time for a population with drug treatments
(79.11 , 112.69)
