The mean of the exponential distribution used in reliability engineering is used as mean time to failure. Correct Answer True

In reliability engineering, the exponential distribution is used as a model of the time to failure of a system. The mean of the distribution is called MTF or mean time to failure.

In the question below, are given a passage followed by three courses of actions numbered I, II and III. On the basis of the information given, you have to assume everything in the statement to be true, and then decide which of the following suggested courses of actions logically follow(s) for pursuing. Passage: Many Engineering graduates in India ends up doing anything but Engineering jobs. Some switch to entirely unrelated fields of work like Finance or Arts but most of them are unemployed. A recent survey has highlighted that among the unemployed graduates, 66% are Engineers while only 10% of the Engineering graduates do Engineering jobs. Courses of action:  I. A law must be passed banning Engineering graduates from taking up other professions. II. The Government must appoint a committee to find out the reasons for these findings. III. A law must be passed to close all Engineering Colleges with less than 5% core job placement rate.
In an opencast mine, dumpers arrive at a shovel location with an average arrival rate of 12 per/hour. The inter-arrival times of the dumpers follow an exponential distribution. The service times of the shovel also follow an exponential distribution with an average of 3 minute. The average waiting time of a dumper in the queue in minutes is
