The path of a race will be drawn on a coordinate grid like the one shown below. the starting point of the race will be at (−5.3, 1). the finishing point will be at (1, −5.3). a four-quadrant coordinate grid is drawn from negative 4 to positive 4. quadrant i is labeled quadrant p, quadrant ii is labeled quadrant q, quadrant iii is labeled quadrant r, and quadrant iv is labeled quadrant s. part a: use the grid to determine in which quadrants the starting point and the finishing point are located. explain how you determined the locations. (6 points) part b: a checkpoint will be at (5.3, 1). in at least two sentences, describe the difference between the coordinates of the starting point and the checkpoint, and explain how the points are related. (4 points)

Atechnician compares repair costs for two types of microwave ovens (type i and type ii). he believes that the repair cost for type i ovens is greater than the repair cost for type ii ovens. a sample of 6767 type i ovens has a mean repair cost of $79.79$⁢79.79. the population standard deviation for the repair of type i ovens is known to be $19.18$⁢19.18. a sample of 5555 type ii ovens has a mean repair cost of $75.24$⁢75.24. the population standard deviation for the repair of type ii ovens is known to be $21.40$⁢21.40. conduct a hypothesis test of the technician's claim at the 0.050.05 level of significance. let μ1μ1 be the true mean repair cost for type i ovens and μ2μ2 be the true mean repair cost for type ii ovens. step 2 of 4 : compute the value of the test statistic. round your answer to two decimal places.
