Given that the explanatory variable x is a workers commute time in minutes and the response variable, y, is the score in a well-being survey. The least squares regression line is: well being =-0.0479(commute time)+69.0296. Name the slope and interpret it in the context of the problem. Use a complete sentence

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.
