How many sprints from rest to a speed of 5.0 m/s would a 65-kg woman have to complete to burn off 5.0 x 10^2 Calories? (Assume 100% efficiency in converting food energy to mechanical energy.)

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

True or false graphs must include scales that increase by the same amount
