Taking expectations of both sides of the preceding yields, upon using the fact that for any random variable W,E[W2]=Var(W)+(E[W])2, (n−1)E[S2]=E[∑i=1nXi2]−nE[X‾2]=nE[X12]−nE[X‾2]=nVar(X1)+n(E[X1])2−nVar(X‾)−n(E[X‾])2=nσ2+nμ2−n...
The standard deviation of a random variable XX is defined as SD(X)=σX=Var(X)−−−−−−√.SD(X)=σX=Var(X).The standard deviation of XX has the same unit as XX. For XX and YY defined in Equations 3.3 and 3.4, we have ...
Variance is used to describe the spread of the data set and identify how far each data point lies from the mean. Covariance shows us how two random variables will be related to each other. It measures how one variable will get affected due to a change in the other random variable. If ...
Let random variable X be normal with mean 105 and variance 25. Find the probability P (110.5 < X < 111.5) (Use MATLAB build - in function normcdf). Normal distribution: A random variable X is said to be normally distributed...

A system of inventory variance detection modeling is described. The system comprises a server computer, a processor, a memory, and an application stored in the memory that, when executed by the proces
Four different types of smiles (neutral, false, felt, miserable, on leniency) were shown. In this experiment, "Type of Smile" is the independent variable. In describing an ANOVA design, the term factor is a synonym of independent variable. Therefore, "Type of Smile" is the factor in this...
Draw a scatter diagram treating MRI count as the explanatory variable and IQ as the response variance. Label the graph. ScatterPlot: Whenever we need to figure the type of relationship that two variables hold with each other, the first step we do ...
