The expected value of a discrete random variable X, symbolized as E(X), is often referred to as the long-term average or mean (symbolized as μ). This means that over the long term of doing an experiment over and over, you would expect this average. For example, let X = the number of heads you get when you toss three fair coins.
26 sty 2022 · The t distribution can be used for inference when working with the standardized difference of two means if (1) each sample meets the conditions for using the t distribution and (2) the samples are independent. We estimate the standard error of the difference of two means using Equation \ref{5.27}.
In summary, in the various examples throughout this lesson, we have calculated the power of testing \(H_0:\mu=100\) against \(H_A:\mu>100\) for two sample sizes ( \(n=16\) and \(n=64\)) and for three possible values of the mean ( \(\mu=108\), \(\mu=112\), and \(\mu=116\)). Here's a summary of our power calculations:
21 paź 2023 · E notation is the same as scientific notation where a decimal number between 1 and 10 is multiplied by 10 raised to some power. In E notation the "times 10 raised to a power" is replaced with the letter e in either uppercase or lowercase. The number after the "e" indicates how many powers of 10.
