Answer:
Divide the standard deviation of the sample measures by 8
Step-by-step explanation:
Given
measurements in data set=500
measurements in sample=64
Standard error of sample=?
As per the formula of standard error
Standard error= standard deviation/ square root of the number of measurements
= σ/√n
Here as we need to find standard error of the sample hence n=64
therefore √64= 8
The above equation will become:
standard error of the sample= σ/8 i.e. Divide the standard deviation of the sample measures by 8!
I'll explain how, if you want the answers to fact check, ask in the comments.
If the first number is in the ones place, and there's no notation, it's 10^0 (number * 1), if the first number is in the tens place, it's 10^1 of the number if it was pushed back into the ones place. If the first number is in the hundreds place, it's 10^2 if it was...
You might get the idea, same applies to negative powers of 10:
If the first number is in the tenths place, it's 10^-1, if the beginning of the number was moved forwards into the ones place, and so on.
I hope I helped you, please ask questions if you need them, I might have delivered a confusing explanation.
