B. (Round off to 3 decimal places) A 75m course, AB, on level ground was paced by a surveyor for the purpose of determining his pace factor. The number of paces for each trial taken are shown in the accompanying tabulation. Determine the following: a) Determine his pace factor. b) If the surveyor then took 350, 351, 352, 353, 354, 350 paces in walking an unknown distance CD, what is the length of the line? c) Assuming that the taped length of the line CD is 325m, determine the relative precision of the measurement performed. TRIAL LINE TAPED NO. OF PACES NO. OF PACES DISTANCE (m) AB 80 350 2 ВА 81 351 3 AB 85 352 75 4 ВА 83 353 5 AB 82 354 ВА 80 350
