A research scientist wants to know how many times per hour a certain strand of bacteria reproduces. He wants to construct the 95%95% confidence interval with a maximum error of 0.190.19 reproductions per hour. Assuming that the mean is 6.46.4 reproductions and the standard deviation is known to be 1.81.8, what is the minimum sample size required for the estimate? Round your answer up to the next integer.

109 is the nearest whole number/final answer! : )

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.
