Question

2. Points) Consider the following sets of three measurement of the acceleration due to gravity made by (20 four students named David, Ryan, Jasmine, and Keiara. The standard value for the acceleration due to gravity is 9.80 m/s2. Find the means, the sample standard deviations and the standard errors for each student. David Ryan Jasmine Keiara 9.86 11.61 8.87 Measurement 1 Measurement 2 Measurement 2 Mean 8.75 9.538.77 9.70 7.83 8.70 9.72 88 Standard Deviation Standard Error hich student is the most accurate? Why? Which student is the most precise? Why? hich student has a systematic error in his/her measurements? Why?

Explanation / Answer

for david, mean = (8.87+9.53+9.38)/3 = 9.26

standard deviation = sqrt [{ (9.26-8.87)^2+(9.26-9.53)^2+(9.26-9.38)^2}/3] = 0.282

standard error = 0.282/sqrt (3) = 0.163 , here no of observation =3

solve like this, for ryan, jasmine and keiara
