14,700 millimeters
58,800/4 = 14,700
Answer: The size of sample is 50
Step-by-step explanation:
Since we have given that
Variance of a sample was reported = 144
Variance of population was reported = 7200
Let the sample size be 'n'.
As we know the formula for "Variance of a sample":
![V(X)=\frac{\sigma^2}{n}\\\\144=\frac{7200}{n}\\\\n=\frac{7200}{144}\\\\n=50](https://tex.z-dn.net/?f=V%28X%29%3D%5Cfrac%7B%5Csigma%5E2%7D%7Bn%7D%5C%5C%5C%5C144%3D%5Cfrac%7B7200%7D%7Bn%7D%5C%5C%5C%5Cn%3D%5Cfrac%7B7200%7D%7B144%7D%5C%5C%5C%5Cn%3D50)
Hence, the size of sample is 50.
Well, an easier way than to divide fractions is to multiply the fractions, but to do that, flip the numerator and denominator for the second fraction.
For example, it becomes: 7 48 2
-------- × -------- = --------- (top×top & bottom×bottom)
