Question 1161780: J.J. Thomson (1856 - 1940) discovered the electron by
negatively charged particles for which he could measure
the mass - change ratio. The ratio appeared to be
constant over a wide range of experimental conditions
and consequently could be characteristics of a new
particle. His observations from two cathode ray tubes
that used air as the gas arethat used air as the gas are
Tube 1 0.57 0.34 0.43 0.32 0.48 0.40 0.40
Tube 2 0.53 0.47 0.47 0.51 0.63 0.61 0.48
(i) Draw dot diagram with solid dots for Tube 1
observations and circles for Tube 2 observations.
(ii) Calculate the mean and standard deviation for the
Tube 1 observations.
(iii) Calculate the mean and standard deviation for the
Tube 2 observations. Answer by CPhill(2285) (Show Source):
