i need help in all those pls

Answer 1

measured Grant 4 And 8) 6.5 percent ennon 7 penent enron = measured value - known value x 100 7. known value 65-61 - y looy. on = 6.5% (Ars) 61 quantity = average I standared deviation, 6 percentage enron expressed as positive in many cases. pereent ennon = 100 - 94.3 - 8100 = 5.70%. (Ang) 100 7) True The stand and deviation measunes how widely spread data points are
