a homeowner has an octagonal gazebo inside a circular area. each vertex of the gazebo lies on the circumference of the
circular area. the area that is inside the circle, but outside the gazebo, requires mulch. this area is represented by the
function m(x), where x is the length of the radius of the circle in feet. the homeowner estimates that he will pay $1.50 per
square foot of mulch. this cost is represented by the function g(m), where m is the area requiring mulch.
m(x) = x2-2./2x2
g(m) - 1,50m

An automobile assembly line operation has a scheduled mean completion time, μ, of 12 minutes. the standard deviation of completion times is 1.6 minutes. it is claimed that, under new management, the mean completion time has decreased. to test this claim, a random sample of 33 completion times under new management was taken. the sample had a mean of 11.2 minutes. assume that the population is normally distributed. can we support, at the 0.05 level of significance, the claim that the mean completion time has decreased under new management? assume that the standard deviation of completion times has not changed.
