Karin is also in Mr. Whittaker’s science class, and she recorded the variation in water level at a different part of the river. Karin observed that the water level there fell 1.68 millimeters per year for 1.5 years. Which expression shows a way to use the distributive property to solve for the total variation in water level at this part of the river? 1.5(-1) + 0.68 1 + (0.5)(-1)(0.68) (-1.68)(1) + (-1.68)(0.5) 1(-1) + 0.5(-0.68)

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.
