instructor if you have questions about any of the solutions given below. 1. Explain the difference between a population and a sample. In which of these is it important to distinguish between the two in order to use the correct formula? mean; median; mode; range; quartiles; variance; standard deviation. Solution: A sample is a subset of a population. A population consists of every member of a particular group of interest. The variance and the standard deviation require that we know whether we have a sample

the right on block 1 with a normal force of 16 N. On a sheet of paper‚ draw the free body diagram for block 1 using the two-subscript notation from class. After completing the free body diagram‚ enter below each force and its x & y-components. Remember that the x-component is the "i" component and the y-component is the "j" component.

Normal Distribution Normal distribution is a statistics‚ which have been widely applied of all mathematical concepts‚ among large number of statisticians. Abraham de Moivre‚ an 18th century statistician and consultant to gamblers‚ noticed that as the number of events (N) increased‚ the distribution approached‚ forming a very smooth curve. He insisted that a new discovery of a mathematical expression for this curve could lead to an easier way to find solutions to

Could Hitler have been stopped? Here are three ways how Hitler could have been stopped like childhood dream ruined‚ being killed in World war one‚ and another country stopping the holocaust. During World war one a British soldier saw a wounded Hitler‚ and refused to shoot him because he said: “I can’t shoot a wounded man.” If the man shoots twenty-year-old Hitler this world would have been a different place.
