The price p of a good and the quality q of a good are linked. the demand for a new pair of trainers can be modelled using the equation p= (-3/4)q+35 the supply of trainers can be modelled using the equation p= (2/3)q+1. they meet on the same pair of axes. the equilibrium point is the point whereto supply and demand lines meet find the values of p and q at the equilibrium point.

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.
