Answer:
CI= [28.67,45.33]
Step-by-step explanation:
-Given the mean is $37 and the standard deviation is $17
#A 95% confidence interval can be calculated as follows:
![CI=\mu\pm z \frac{\sigma}{\sqrt{n}}\\\\=\mu\pm z_{0.025}\frac{\sigma}{\sqrt{n}}\\\\=37\pm1.96\times\frac{17}{\sqrt{16}}\\\\\\=37\pm8.33\\\\=[28.67,\ 45.33]](https://tex.z-dn.net/?f=CI%3D%5Cmu%5Cpm%20z%20%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D%5C%5C%5C%5C%3D%5Cmu%5Cpm%20z_%7B0.025%7D%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D%5C%5C%5C%5C%3D37%5Cpm1.96%5Ctimes%5Cfrac%7B17%7D%7B%5Csqrt%7B16%7D%7D%5C%5C%5C%5C%5C%5C%3D37%5Cpm8.33%5C%5C%5C%5C%3D%5B28.67%2C%5C%2045.33%5D)
Hence, the 95% confidence interval is [28.67,45.33]
Answer:
The answer is 351/5. But if you want to simplify it, it would be the same thing
Answer:
1056.25π square units
Step-by-step explanation:
A few formulas an definitions which will help us:
(1) 
, where c is the circumference of a circle and d is its diameter
(2) 
, where A is the area of a circle with radius r. To put it in terms of d, remember that a circle's diameter is simply twice its radius, or mathematically, (3) 
.
We can rearrange equation (1) to put d in terms of π and c, giving us (4) 
, and we can make a few substitutions in (2) using (3) and (4) to get use the area in terms of the circumference and π:
We can now substitute c for our circumference, 65, to get our answer in terms of π:

The answer is a
