Question

The normal distribution is an appropriate model​ of: A. system reliability where components are connected in parallel. B. the full cost view of maintenance. C. the high initial failure rates of​ product, machine, or processes. D. the MTBF distribution of​ products, machines, or processes that have​ "settled in." E. system reliability where components are connected in series.

Answer 1

Answer:

The correct answer is the option D: the MTBF distribution of products, machines, or processes that have "settled in".

Explanation:

To begin with, the term of "normal distribution" refers to statistic model used in the field of probabilities and the most common characteristics are that they have a standard deviation of 1 and are all symmetrical. In the proper graphic the form of a normal distribution will be the one of a curve bell. Therefore that it is regularly seen in as an appropiate model of MTBF distribution regarding maintenance of products, machines or processes. Moreover, this distribution also known as Gaussian is motivated by the Central Limit Theorem.
