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:
13 / 8
Step-by-step explanation:
Given that :
Length of board = 13 feets
Number of equal board section needed = 8
The largest possible length of 1 section of the board :
Since each section are the same :
Length of board / number of board sections
= 13 / 8
{ y ≥ 2x + 1; y > -2x - 3 } Unbound

First:
A graph that starts y< or y> will always be a dashed line, because the points on the line do not make the equality true.
A graph with y≤ or y≥ will have a solid line.
Second,:
If the equation is y<, then the shading will be below the line. (If you were standing on the line, you'd look straight down for the solutions.)
If the equation is y>, then the shading will be above the line. (If you were standing on the line, you'd look straight up for the solutions.)
For your exercise:
Neither A nor B fits that inequality. I hope there are options C and D
