Will give a ! why does the formula use “n – 1” in the denominator? the data is a sample and is expected to be more dispersed from the mean. the data is a sample and is expected to be less dispersed from the mean. the data is a population and is expected to be more dispersed from the mean. the data is a population and is expected to be less dispersed from the mean.

Answer with explanation:

Formula to find variance of Population

Formula to find variance of a Sample

The meaning of the word Variance, is how dispersed the variate are from mean.

Option A

The data is a sample and is expected to be more dispersed from the mean.

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
