Answer:
- 0.0062AU
- 0.00082.
- 106.7% error
Explanation:
a.) Average or mean value of readings, = (0.0044 + 0.0079 + 0.0062) / 3
= = 0.0062 AU
b.) The accuracy of the readings is determined by taking determining the standard deviation (SD) of the readings:
SD = ∑ /n
= 0.0000032
= 0.00000289
= 0
SD = = 0.00082.
c.) The % accuracy is the distance between the average value and true value
= = 106.7% error.
