Consider the following data for two independent random samples taken from two normal populations. sample 1 10 7 13 7 9 8 sample 2 8 7 8 4 6 9 compute the two sample means. sample 1: sample 2: compute the two sample standard deviations (to 2 decimals). sample 1: sample 2: what is the point estimate of the difference between the two population means? what is the 90% confidence interval estimate of the difference between the two population means? if required enter negative values as negative numbers (to 2 decimals). use z-table. ( , )

the anwser is d) 75°

step-by-step explanation:

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.

greater than one
