Answer:
... anything less than 2.98??
Step-by-step explanation:
Answer:
22 ft
Step-by-step explanation:
To find the length of the side of a square you need to do the opposite equation for finding area.
So the equation for finding the area of a square is a - x^2, or a = x squared.
The opposite of this equation would be x = square root of 479 because the opposite operation of squared is square root.
Now you need to solve this equation
So x = square root of 479, the square root of 479 is 21.89
So the x equals 21.89 but you need to find the approximate length so you need to round. It says to round to the nearest foot so one side of the square is 22 feet long.

Answer:
99% confidence interval is:
(0.00278 < P1 - P2< 0.15921)
Step-by-step explanation:
For calculating a confidence intervale for the difference between the proportions of workers in the two cities, we calculate the following:
![[(p_{1} - p_{2}) \pm z_{\alpha/2} \sqrt{\frac{p_{1}(1-p_{1})}{n_{1}} + \frac{p_{2}(1-p_{2})}{n_{2}} }](https://tex.z-dn.net/?f=%5B%28p_%7B1%7D%20-%20p_%7B2%7D%29%20%5Cpm%20z_%7B%5Calpha%2F2%7D%20%5Csqrt%7B%5Cfrac%7Bp_%7B1%7D%281-p_%7B1%7D%29%7D%7Bn_%7B1%7D%7D%20%2B%20%5Cfrac%7Bp_%7B2%7D%281-p_%7B2%7D%29%7D%7Bn_%7B2%7D%7D%20%7D)
Where
: proportion sample of individuals who worked
at more than one job in the city one
: Number of respondents in the city one
: proportion sample of individuals who worked
at more than one job in the city two
: Number of respondents in the city two
Then
α = 0.01 and α/2 = 0.005
and ![z_{\alpha/2} = 2.575](https://tex.z-dn.net/?f=z_%7B%5Calpha%2F2%7D%20%3D%202.575)
![p_{1} = \frac{112}{384} = 0.2916](https://tex.z-dn.net/?f=p_%7B1%7D%20%3D%20%5Cfrac%7B112%7D%7B384%7D%20%3D%200.2916)
![p_{2} = \frac{91}{432} = 0.2106](https://tex.z-dn.net/?f=p_%7B2%7D%20%3D%20%5Cfrac%7B91%7D%7B432%7D%20%3D%200.2106)
and ![n_{2}= 432](https://tex.z-dn.net/?f=n_%7B2%7D%3D%20432)
The confidence interval is:
![[(0.2916 - 0.2106) \pm 2.575 \sqrt{\frac{0.2916(1-0.2916)}{384} + \frac{0.2106(1-0.2106)}{432} }](https://tex.z-dn.net/?f=%5B%280.2916%20-%200.2106%29%20%5Cpm%202.575%20%5Csqrt%7B%5Cfrac%7B0.2916%281-0.2916%29%7D%7B384%7D%20%2B%20%5Cfrac%7B0.2106%281-0.2106%29%7D%7B432%7D%20%7D)
(0.00278 < P1 - P2< 0.15921)
