Answer:
............................
Step-by-step explanation:
The answer would be D because all sides are equivalent.
Answer:
a) n = 100
![\bar{x} = 58](https://tex.z-dn.net/?f=%5Cbar%7Bx%7D%20%3D%2058)
s = 8
Confidence interval = 95%
Z at 95% = 1.96
Confidence interval formula :
to ![\bar{x}-z\frac{s}{\sqrt{n}}](https://tex.z-dn.net/?f=%5Cbar%7Bx%7D-z%5Cfrac%7Bs%7D%7B%5Csqrt%7Bn%7D%7D)
Substitute the values :
Confidence interval :
to ![58+1.96 \times \frac{8}{\sqrt{100}}](https://tex.z-dn.net/?f=58%2B1.96%20%5Ctimes%20%5Cfrac%7B8%7D%7B%5Csqrt%7B100%7D%7D)
Confidence interval :
to ![59.568](https://tex.z-dn.net/?f=59.568)
b)n = 200
![\bar{x} = 62](https://tex.z-dn.net/?f=%5Cbar%7Bx%7D%20%3D%2062)
s =11
Confidence interval = 90%
Z at 90% = 1.64
Confidence interval formula :
to ![\bar{x}-z\frac{s}{\sqrt{n}}](https://tex.z-dn.net/?f=%5Cbar%7Bx%7D-z%5Cfrac%7Bs%7D%7B%5Csqrt%7Bn%7D%7D)
Substitute the values :
Confidence interval :
to
Confidence interval :
to ![63.275](https://tex.z-dn.net/?f=63.275)
Answer:
[0,11]
Step-by-step explanation:
Required
Represent Set of numbers from 0 to 11
<em>In interval notation; the square bracket [ ... ] implies that the number in question is inclusive of the set.</em>
So; Given that
Beginning = 0
End = 11
The interval notation can be represented as [0,11] because both numbers are inclusive of the set.
