The graph below represents the distance a pilot is from the home airport during a period of time. A graph titled Pilot's Distance from Home. The horizontal axis shows time (hours) and the vertical axis shows distance (miles). Both axes are unnumbered. A line is shown in 3 sections, labeled I, II, and III. Sections I and III show a reduction in distance over time and section II is constant. Which describes the pilot’s distance in section I? zero constant decreasing increasing

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.
