Answer:
False
Step-by-step explanation:
Steps in calculating confidence Interval are
- Calculate degree of freedom by subtracting 1 from sample size that is df=sample size -1
- find α by subtracting confidence interval level from 1 and divide by 2
- Use value ot α and df to determine t from t-distribution table. From table it can be seen that the value of t increases as value of df decreases
- Divide standard distribution by square root of sample size. As sample size decreases this value will increase
- Multiple step 3 by step 4. We can say, if sample size is decreased this value will increase.
- For lower end , subtract step 5 from sample mean and for upper end add step 5 to sample mean.
If sample size is decrased, step 3 and step 4 will increase. As a result result obtained from step 5 will also increase. Hence, confidence interval will increase if sample size is decreased

Answer:
![s\geq 4\ cm](https://tex.z-dn.net/?f=s%5Cgeq%204%5C%20cm)
Step-by-step explanation:
we know that
![s(V)=\sqrt[3]{V}](https://tex.z-dn.net/?f=s%28V%29%3D%5Csqrt%5B3%5D%7BV%7D)
where
s is the side length, in units, of a cube
V is the volume of a cube in cubic units
For a
substitute in the formula
![s=\sqrt[3]{64}](https://tex.z-dn.net/?f=s%3D%5Csqrt%5B3%5D%7B64%7D)
![s=4\ cms](https://tex.z-dn.net/?f=s%3D4%5C%20cms)
If Jason wants to build a cube with a minimum of 64 cubic centimeters
therefore
the minimum length side of the cube is 4 cm
![s\geq 4\ cm](https://tex.z-dn.net/?f=s%5Cgeq%204%5C%20cm)
Answer:
19 1/6
Step-by-step explanation:
Because 15 divided by 180 is 0.08333333333.
times that by 230 = 19.166666666 or 19 1/6
