The n-1 indicates that the calculation is being expanded from a sample of a population to the entire population. Bessel's correction(the use of n − 1 instead of n in the formula) is where n is the number of observations in a sample: it corrects the bias in the estimation of the population variance, and some (but not all) of the bias in the estimation of the population standard deviation.
That is, when estimating the population variance and standard deviation from a sample when the population mean is unknown, the sample variance is a biased estimator of the population variance, and systematically underestimates it.

What is the sum of the 10 positive integers?
The sum of the first 10 positive integers, using the formula N1 + (N1 + 1) + ... + N2 = N2 * (N2 + 1) / 2 - (N1 - 1) * N1 / 2 is: 55
What difference between a favorable variance and an unfavorable variance?
Favourable variance is that variance which is good for business while unfavourable variance is bad for business
How do you solve N to the 30th divided by N to the first?
You subtract the exponents. N30 - N1 = N30 - 1 = N29.You subtract the exponents. N30 - N1 = N30 - 1 = N29.You subtract the exponents. N30 - N1 = N30 - 1 = N29.You subtract the exponents. N30 - N1 = N30 - 1 = N29.

What can you include in calculation to indicate which calculation should be done first?
Parentheses
What does a favorable direct materials efficiency variance indicate?
A favorable direct materials efficiency variance indicates that you are using less material in production than was budgeted for.
What is the significance of variance in statistics?
Variance is a measure of "relative to the mean, how far away does the other data fall" - it is a measure of dispersion. A high variance would indicate that your data is very much spread out over a large area (random), whereas a low variance would indicate that all your data is very similar.Standard deviation (the square root of the variance) is a measure of "on average, how far away does the data fall from the mean". It can be interpreted in a similar way to the variance, but since it is square rooted, it is less susceptible to outliers.
Codings for coprime number in c?

What is the pmf of trinomial distribution?
P(x=n1,y=n2) = (n!/n1!*n2!*(n-n1-n2)) * p1^n1*p2^n2*(1-p1-p2) where n1,n2=0,1,2,....n n1+n2<=n
What does a debit balance in the labor efficiency variance account indicate?

Find LCM and HCF of two given number by using for loop in c?
#include<stdio.h> int main(){ int n1,n2; printf("\nEnter two numbers:"); scanf("%d %d",&n1,&n2); while(n1!=n2){ if(n1>=n2-1) n1=n1-n2; else n2=n2-n1; } printf("\nGCD=%d",n1); return 0; }
What is the value of the expression n1?
the value of the exponent n1
What is the value of the expression of n1?
the value of the exponent n1
In the calculation of variances why are they squared?
Try calculating the variance without the squaring bit - it gives 0 every time. Squaring allows you to ignore the direction (sign) of the number.
What is the sum of the 10 positive integers?
The sum of the first 10 positive integers, using the formula N1 + (N1 + 1) + ... + N2 = N2 * (N2 + 1) / 2 - (N1 - 1) * N1 / 2 is: 55
