A person infers that the length of a rod is 4.4973 (plus/minus) 0.0014 cm. (1 sigma). What is the probability that the true length of the rod is actually greater that 4.500 cm? I am a confused as to what this question is asking you to do. Also, is the 1 sigma (1 standard deviation) significant? Any help would be much appreciated!

1. The service manager for Air Canada is uncertain about the time needed for the ground crew to turn an airplane around from the time it lands until it is ready to take off. He has been given information from the operations supervisor indicating that the times seem to range between 20 and 45 minutes. Without any further information, the service manager will apply a uniform distribution to the turnaround. (a) Define the density distribution/function. (b) What is the probability...

A. Introduction and Objective Every test has at least two sources of variation that affect the results of the test. The first source of variation is due to the experimental procedure, such as using two different testing machines that have different calibrations, or different observers reading the same equipment differently. This type of variation is often called the experimental error The second source of variation is inherent in the specimens (or sample population) themselves. In other words, no two specimens...

1. Short answer only.a. Suppose that we tell you that we flipped a coin multiple times and it landed heads 75% of the time. Would you be reasonably convinced that this was not a fair coin (where “fair” means that the coin has a .5 probability of landing “heads”)? If so, explain why. If not, describe what additional information you would ask for and explain why it is necessary.b. A college professor asked students in his class to report how...
