Measured force data for exercise problems

Assignment Help Mechanical Engineering

Reference no: EM13704626

From the data in column 1, determine the best estimate of the mean value at a 95% probability level.

How does this estimate differ from the estimates made in problem 4.11? Repeat for columns 2 and 3.

Why do the estimates vary for each data set? Discuss these outcomes in terms of what you might expect from finite statistics if these are measuring the same measured variable during the same process.
