Lyles College of Engineering GME, 15 Exam #1 7, which of the following is not true? a) matic errors can be modeled mathematically onditions change, c) Random error remains after will remain constant all systematic errors and biases and mistakes have been eliminated d) Random errors follow general laws of probability and are present in observations which if the following is true about residuals? a small residuals occur more often b) Large residuals occur more often c) Positive and negative residuals occur with similar frequencies d) residuals can be measured which closely resembles systematic 9. Given 3 segments of a line, ab 32.13 t 0.02 be 599,23 t 1.23, and cd 4699 t 0.17 what is the length of the line ac? a) 678.35 t 1.24 b) 678.35 t 1.25 c) 631.36 t 1.23 d) 631.36 t 1.42 10. have an instrument that is a 10\" total station, meaning that I can measure to the nearest 00 00\'10\". In running a traverse, I measure 50 angles, and am required to keep my error below 00 01 00\". lf my error is the same for each angle, to what precision must l not exceed in measuring each angle? Can I accomplish this survey using my instrument? a) t 8.5\" and No. b) t 12\" and Yes c) t 12 and No d) 10.14\" and Yes 11. Given that the most probable value is 13,1254m, which of the following observations is the most accurate? a) 13,1255m b) 13. 1250m c) 13,1254m d) 13.125m Professor Peterson -22617-Evam -GME 15

Solution

a) Since systemetic errors are caused by the physics of the measurement sysem, hence the can be mathematically modeled. So the given statement is TRUE.

b) As long as the measuring system remains constant, systemetic error remains constant. If the condition changes, the magnitude of systemetic error will also change. So the given statement is FALSE.

c) TRUE

d) TRUE
