7.2 For a direction with sight distances to targets of 100, 200, 300, 400, 600, 1000, and 1500 ft, construct: (a) a table of estimated standard deviations due to target centering when od=±0.005 ft. (b) a plot of distance versus the standard deviations computed in part (a).

kindly answer immediately, thankyou so much, in the surveyig subject   -Problem ABCDE6. A student counted 50, 52, 53, 51, 53, and 51 paces in walking along a 45-m course laid out on a concrete pavement. The student took 768, 771, 770, 769, and 770 paces in walking an unknown distance AB. What is the the average pace is 51.67 now, On Problem ABCDE6. The student took 768, 771, 770, 769, and 770 paces in walking an unknown distance AB. His pace factor should be equal to choices: a. 0.871, b. 0.860, c. 0.875, d. none of the above -On Problem ABCDE6. The length of AB based on pace factor of the student is equal to choices: a. 670.32, b. 670.34, c. 670.33, c. none of the above
