To find the probability of drawing a person from any group, take the number in that group and divide by the total number of people. There are 80 total people in your example. P(secy) = 4/80 = 0.05 P(tech) = 20/80 = 0.25 P(engr) = 4/80 = 0.05 P(exec) = 2/80 = 0.025 P(fact worker) = 50/80 = 0.625

What is 2.25 L rounded to nearest tenth?

It is 2.2 L.Although many schools teach you to round 5 up, always rounding up from 5 is inappropriate because it introduces an upward bias. The IEEE (Institute of Electronic and Electrical Engineers) standard 754 is to round 5 up or down so that the new last digit is even.

What is the difference between data warehouse testing and conventional testing?

ETL stands for Extract-Transform-Load and it is a process of how data is loaded from the source system to the data warehouse. Data is extracted from an OLTP database, transformed to match the data warehouse schema and loaded into the data warehouse database.Many data warehouses also incorporate data from non-OLTP systems such as text files, legacy systems and spreadsheets. Conventional testing is a sort of testing in which the test engineers will check the developed application or its related parts are working accordingly to the expectations of customer or not, from coding phase of SDLC to the end

What is the difference between engineer and technician?

The difference between Engineers and Technicians is not that one is more hands-on or practical than the other. Rather, the fundamental difference between the two is that Engineers develop/design systems while Technicians support those systems. As such, Engineering and Technology are complementary fields. Engineers need to start from a theoretical framework in order to develop/design systems while technicians need to understand how those systems work in order to support them. That fundamental difference between Engineering and technology not only explains how or why engineers tend to rise to top management but also gives engineers a career advancement advantage because engineers by designed manage the development and implementation of their systems, which are to be supported by technicians.
