What does hubble's law tell us?
a) the faster a spiral galaxy's rotation speed, the more luminous it is.
b) the longer the period of a cepheid variable, the greater its luminosity.
c) for every force, there is an equal and opposite reaction force.
d) the more distant a galaxy, the faster it is moving away from us. old, red, and bright and have fewer heavy elements.

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error
