The box plots represent the ages of pennies in two 50-cent rolls. By looking at the plots, Beth says that the two means are about 5 years apart. Which is true about Beth’s statement? A/ She is correct because the medians are 10 years apart, which means the means are half of that, or 5 years apart. B/ She is correct because the maximum ages of the pennies in each set are 5 years apart. C/ She is not correct because the means are both equal to 12. D/ She may not be correct because means cannot be determined from the box plots.

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.
