Question 1011188: Q)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 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

Dot plot is using a dot on a number line
mean for tube 1 is 0.42
sd=0.085
mean for tube 2 is 0.53
sd for tube 2 is 0.066
