Variables:

Equation and Solve:

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

What is the orbital period of a spacecraft in a low orbit near the surface of mars? the radius of mars is 3.4×106m.
