He table represents the height of a ball that is dropped, h(t), after t seconds.
A 2-column table with 6 rows. The first column is labeled x with entries 0, 1, 2, 3, 4, 5, 6. The second column is labeled h(t) with entries 150, 145.1, 130.4, 105.9, 71.6, 27.5, negative 26.4.
Determine the initial height of the ball and the time interval before the ball hits the ground.
initial height = 0; hits the ground between 5 and 6 seconds
initial height = 150; hits the ground between 5 and 6 seconds
initial height = 0; hits the ground between 3 and 4 seconds
initial height = 150; hits the ground between 4 and 5 seconds

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.
