Point Q is plotted on the coordinate grid. Point P is at (50, β30). Point R is vertically above point Q. It is at the same distance from point Q as point P is from point Q. Which of these shows the coordinates of point R and its distance from point Q? (1 point) On a coordinate grid from negative 50 to positive 50 in increments of 10, Point Q is plotted at the ordered pair negative 20, negative 30. Group of answer choices Point R is at (β20, β10), a distance of 20 units from point Q Point R is at (β20, β40), a distance of 70 units from point Q Point R is at (β20, 10), a distance of 20 units from point Q Point R is at (β20, 40), a distance of 70 units from point Q

An automobile assembly line operation has a scheduled mean completion time, ΞΌ, 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.
