USE THE INFORMATION BELOW TO ANSWER QUESTIONS 28 THRU 30 Using satellite imagery to aid agriculture grain production has been done on a limited scale as far back as the 1970's when NASA first launched the Landsat satellite. But it has only been recently that the satellite images, including GPS satellites, and data from typical farm operations have been integrated together to provide a data driven innovative technology that improves the efficiency and productivity on farms. In one study samples were taken on wheat yields in the State of Washington which historically had average yields of 35.6 bushels per acre with a standard deviation of 3.7 bushels per acre. Suppose that a random sample of the wheat yields on 40 different farms was taken and the sample mean for the wheat yields was computed, and you are interested in a probability about the sample mean. Question 28 1 pts Pick the equation most appropriate to deal with the problem above. O z - 2-1 Op(x) = nCap" (1 -p)" a Ox = 1 + zo O z =
