Which of the statements about normal error distribution is false?
Theory and Design for Mechanical Measurements
Measurement is a term that refers to analyzing a manufactured component regarding the degree of accuracy for dimensions, tolerances, geometric profile, roundness, flatness, smoothness, etc. Measurement always involves comparing the manufactured component or the prototype with a standard specimen whose dimensions and other parameters are assumed to be perfect and do not undergo changes with respect to time.Precisely in mechanical engineering the branch that deals with the application of scientific principles for measurements is known as metrology. The domain of metrology in general deals with various measurements like mechanical, chemical, thermodynamic, physical, and biological measurements. In mechanical engineering, the measurements are limited to mechanical specific such as length, mass, surface profile, flatness, roundness, viscosity, heat transfer, etc.
Basic principles of engineering metrology
Metrology is described as the science of measurement, precision, and accuracy. In other words, it is a method of measurement based on units and predefined standards.

Which of the statements about normal error distribution is false?
O A) The standard nomal distrībution belongs to the special case where the standard deviation is zero.
O B) The standard nomal distribution belongs to the special case where the mean is zero.
O C) The graph of the normal distribution function is defined between - and + *.
-D0
O D) The area under the curve in the graph of the normal distribution function gives the probability of recurrence of a certain eror.
O E) Since the graph of the nomal distribution function looks like a bell, it is known as the bell curve.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F280beb6e-731c-43d3-9d27-abada8025134%2F4e64aefe-5b6b-476f-962f-74364a42f365%2Fcetahfg_processed.jpeg&w=3840&q=75)
