Suppose σ=36 and sample size n = 81. what is the standard error (s. e) of x ̅?

The standard error of the mean is labelled as: σM. The formula for the standard error is: where σ is the standard deviation of the original distribution and n is the sample size. The formula is σ / square root n

So the given in our problem is:

σ=36

n = 81

Standard Error = 36 / sqrt81

= 36 / 9

= 4

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1
