Acertain type of lightbulb is advertised to have mean lifetime of 750 hours. a consumer advocacy group would like to check this claims and test: h0: the mean lifetime is the advertised 750 hours ha: the mean lifetime is less than the advertised 750 hours. the advocacy group chooses at random 40 lightbulbs and records their lifetimes. based on the data the group concludes that the mean lifetime is less than 750 hours and accuses the manufacturer of the lightbulbs in false advertising. what type of error is possible in this situation?

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.

is it like a multiple choice? if so then i need the multiple choice so i can get and understanding on what the answers is so that i can explain it to you
