Answer:
We cannot say that the mean wake time are different before and after the treatment, with 98% certainty. So the zopiclone doesn't appear to be effective.
Step-by-step explanation:
The goal of this analysis is to determine if the mean wake time before the treatment is statistically significant. The question informed us the mean wake time before and after the treatment, the number of subjects and the standard deviation of the sample after treatment. So using the formula, we can calculate the confidence interval as following:
![IC[\mu ; 98\%] = \overline{y} \pm t_{0.99,n-1}\sqrt{\frac{Var(y)}{n}}](https://tex.z-dn.net/?f=IC%5B%5Cmu%20%3B%2098%5C%25%5D%20%3D%20%5Coverline%7By%7D%20%5Cpm%20t_%7B0.99%2Cn-1%7D%5Csqrt%7B%5Cfrac%7BVar%28y%29%7D%7Bn%7D%7D)
Knowing that 
:
![IC[\mu ; 98\%] = 98.9 \pm 2.602\frac{42.3}{4} \Rightarrow 98.9 \pm 27.516](https://tex.z-dn.net/?f=IC%5B%5Cmu%20%3B%2098%5C%25%5D%20%3D%2098.9%20%5Cpm%202.602%5Cfrac%7B42.3%7D%7B4%7D%20%5CRightarrow%2098.9%20%5Cpm%2027.516)
![IC[\mu ; 98\%] = [71.387 ; 126,416]](https://tex.z-dn.net/?f=IC%5B%5Cmu%20%3B%2098%5C%25%5D%20%3D%20%5B71.387%20%3B%20126%2C416%5D)
Note that ![102.8 \in [71.384 ; 126.416]](https://tex.z-dn.net/?f=102.8%20%5Cin%20%5B71.384%20%3B%20126.416%5D)
so we cannot say, with 98% confidence, that the mean wake time before treatment is different than the mean wake time after treatment. So the zopiclone doesn't appear to be effective.
0.10*d + 0.05*d+2(0.05) + 0.01*3d= 0.64
0.18d+0.10=0.64
0.18d= 0.54
d= 3 There are 3 dmes
n= d+2= 5 nickels and
p= 3d= 3*3= 9 pennies
3(0.10)+ 5(0.05)+9(0.01)= 0.64
0.30+0.25= 0.09= 0.64

0.64= 0.64</span>
Answer:
Given that the triangular prism has a base that is a right triangle.The height of the triangular prism is 10 cm.The side lengths of the triangle are 4.3 cm, 5.2 cm and 6.75 cm.We need to determine the surface area of the triangular prism.
Step-by-step explanation: The surface area of the triangular prism can be determined using the formula,where b is the base and h is the height of the triangle.s₁, s₂, s₃ are the side lengths of the triangle andH is the height of the prism.Substituting b = 5.2, h = 4.3, s₁ = 5.2, s₂ = 4.3, s₃ = 6.75 and H = 10 in the above formula, we get SA=(5.2)(4.3)+(5.2+4.3+6.75)(10)
SA=22.36+(16.25)(10)
SA=22.36+162.5
SA=184.86 cm 2Thus, the surface area of the triangular prism is 184.86 square cm.
