Given the information in the illustration and understanding that the gravitational potential energy of an object on Earth can be calculated using the formula PE = m x g x h, in which m = mass in kilograms, g = the acceleration due to gravity, and h = height in meters, what was the change in mechanical potential energy of the spring after the mass was placed on it?

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
