4. The temperature of the Earth at different sites can be measured in two ways. One, by taking readings using thermometers on the ground (x), which is extremely tedious and time consuming. Second, bylasers positioned on satellites revolving about the Earth (v). which ie a less accurate method and may be biased. The readings for both are given below: Ground Therm., x Satellite Laser, y Site 1 4.6 4.7 2 17.3 19.5 3 12.2 12.5 4 3.6 4.2 5 6.2 6.0 6 14.8 15.4 7 11.4 14.9 8 14.9 17.8 emignaia 9 9.3 9.7 10 10.4 10.5 11 7.2 7.4 You would like to test the claim that the Laser method gives a significantly higher reading than the ground therm. method. You may assume that the difference between pairs of scores is approximately normal. A) Would testing for a difference in means or a paired difference test be better to use here? Why? B) Perform the test you concluded in part A). 200 seetV C) Would you have any reservations about yourinference? Why?
