Which of the following SRS designs (sampling without replacement) will give the most precision (smallest standard error) for estimating a population mean? Assume that each population has the same value of the population variance S2. (a) An SRS of size 400 from a population of size 4000 (b) An SRS of size 30 from a population of size 300 (c) An SRS of size 3000 from a population of size 300,000,000 (d) What does this problem illustrate about

$9.41

step-by-step explanation:

21

jk it's 20

step-by-step explanation:

answer4 to the second power is 16

and 4 to the third power is 64,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
