Fraction numbers are known as numerator and denominator

On a number line, fractions are expressed in points that lie between two integers

The general form of fractions is A /B

Decimal numbers can be changed into mixed or ordinary fractions

Mixed fractions consist of integers and ordinary fractions

Decimal numbers have numbers in the form of thousands. Hundreds, tens, thousandths, hundredths, tenths and ones

The results of the division of decimal numbers with numbers 10,100,1000, 10000 and so on can be determined by shifting the comma to the left according to the number of zeros

If you divide a decimal number, you try to make the divisor an integer

Total fencing/week = 42.6 meters

Monday + Tuesday = 13.45+9.5 meters = 22.95 meters

so for 3 days (Wednesday-Friday) = 42.6 - 22.95 = 19.65 meters

Then on eachof the last three days : 19.65 : 3 = 6.55 meters

____ [38]

Answer:

Step-by-step explanation:

Sample variance when large number of samples are drawn we have tend to become a normal distribution.

Variance of the sample is different since variance

Var(x) = E(x^2)-{E(x)}^2

is the formula used for finding the variance of any sample.

But sampling distribution of variance requires repeating this process with the different samples several times.

So option A is not right

B is also not correct, C is wrong

D.The sampling distribution of the mean requires multiple samples to be compared. However, in this situation you are looking for the variance, so finding the sample variance is the same as investigating the sampling distribution of the variance.

is correct
