Answer:
N = 16 measurements
Step-by-step explanation:
A method produces a random error for each measurement of 4%
A percent error of equal to or less than 1% is required.
We want to find out the minimum number of measurements that must be collected.
The standard error is given by
![SE = \frac{S}{\sqrt{N} } \\](https://tex.z-dn.net/?f=SE%20%3D%20%5Cfrac%7BS%7D%7B%5Csqrt%7BN%7D%20%7D%20%5C%5C)
Where s is the standard deviation and N is the number of measurements.
We are given standard deviation equal to 4% and SE equal to 1%
So re-arranging the above equation for N
![\sqrt{N} = \frac{S}{SE} \\N = (\frac{S}{SE})^{2}\\N = (\frac{0.04}{0.01})^{2}\\N = 16](https://tex.z-dn.net/?f=%5Csqrt%7BN%7D%20%3D%20%5Cfrac%7BS%7D%7BSE%7D%20%5C%5CN%20%3D%20%28%5Cfrac%7BS%7D%7BSE%7D%29%5E%7B2%7D%5C%5CN%20%3D%20%28%5Cfrac%7B0.04%7D%7B0.01%7D%29%5E%7B2%7D%5C%5CN%20%3D%2016)
Therefore, a minimum 16 number of measurements are needed.
Answer:
Slope (m) = 0.26470588235294
Step-by-step explanation:
y = 0.26470588235294x + 7.5
or y =
+ ![\frac{15}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B15%7D%7B2%7D)
When x=0, y = 7.5
When y=0, x = -28.333333333333
