How much is the lottery really worth? you have to be careful about money. lottery winners sometimes think they are millionaires when in fact they are not as rich as they think. suppose a state runs a lottery in which the grand prize is $1 million dollars. what that means is that the winner is paid $1 million dollars continuously over the next 20 years. assuming that banks pay interest of 10% on borrowed money over the next 20 years, how much is the lottery worth in today's dollars? hint: letting t denote time in years, first solve s' = 0.10s - 50,000, s(0) = so, and then set s(20) 0 and solve for so

Afactory makes propeller drive shafts for ships. a quality assurance engineer at the factory needs to estimate the true mean length of the shafts. she randomly selects four drive shafts made at the factory, measures their lengths, and finds their sample mean to be 1000 mm. the lengths are known to follow a normal distribution whose standard deviation is 2 mm. calculate a 95% confidence interval for the true mean length of the shafts. input your answers for the margin of error, lower bound, and upper bound.
